ISOLETTE@ Infant lncubator

OPERATING PRECAUTIONS

Federal Law restricts this device to sale by or on the order of a physician. lncubator misuse may result in harm to an infant. Incubators should be used only by properly trained personnel as directed by an appropriately qualified attending physician aware of currently known haz- ards and benefits. The lncubator should not be used if it fails to function properly. Service should be referred to qualified personnel.

Mattress temperature may rise above preset level if Access Panel is left open. Therefore, do not leave open longer than essential. Do not rely on temperature indicator when Access Panel is open. For infant safety DO NOT leave the infant unattended when the Access Panel is open.

When the Access Panel is open, a curtain of warm air flows from beneath the front edge of the mattress toward the top of the Access Panel opening. The temperature of this air curtain is higher than the typical lncubator air temperature, therefore the infant should be kept clear of this warm air path. The lncubator must be attached to the Stand or Cabinet or VHA Stand using the clamps provided. Fail- ure to do so could result in the lncubator separating from the stand if sufficiently tilted, particularly with the hood open. To avoid overheating the infant due to direct radiation, do not position the lncubator in direct sunlight or under other sources of radiant heat. The high air temperature alarm might not be actuated under these conditions. Phototherapy units located too close to the lncubator may affect hood wall temperature, lncubator air temperature and infant skin temperature.

When an X-ray is taken through the hood, the hole in the top of the hood used with the optional sling weighing scale could show up on the X-ray as a radiolucent shadow and could result in incorrect diagno- sis. To prevent harm to the infant, the Hood should not be raised while leads or tubing are connected to the infant or if the mattress is tilted. There should be no need to raise the hood at any time while the infant is cared for in the Incubator. All necessary access to the infant can be achieved by means of the Access Panel and Access Doors. The use of infant seats, head hoods or other accessories within the lncubator which can alter the airflow pattern may affect temperature uniformity, temperature variability, the correlation of the lncubator temperature reading to center mattress temperature and infant skin temperature. Do not lubricate Mattress Tilt Mechanism with oil or other potentially flammable material. Flammability is enhanced in an oxygen-enriched environment.

Be sure that all the thumb screws that secure the Mattress Tilt Mechanism to the Deck are fully tightened to ensure Mattress Tray stability. To minimize the risk of tipping during transport, the Standard Cabinet Stand doors must remain closed during transport. Phototherapy lamps placed over the top of the lncubator hood may interfere with upward travel of the VHA Stand. To prevent this interference, always remove the phototherapy lamp priorto repositioning the elevator. Never place objects taller than the top of the wheel casters beneath the lncubator stand. Placement of these objects here could interfere with stability or operation of the VHA Stand. To avoid possible tip-over or damage to adjacent carts, IV stands, shelves, etc., keep at least a foot (30 cm) perimeter area around the VHA Stand. For optimum lncubator stability, always lock at least two of four VHA Stand wheels during use. When operating the VHA Stand, always place one hand on the lncubator for support to prevent losing balance. To prevent accidental disconnection, secure all patient leads, infusion lines and ventilator tubing to the mattress with sufficient excess length to allow for the full range of mattress height adjustment. When moving the incubator, two persons of sufficient strength are required for adequate control.

OPERATING PRECAUTIONS (continued)

Always lower the lncubator to its lowest position prior to transport for optimum stability. Make sure the swivel monitor shelves are empty.

When using the incubator swivel shelves, exercise the following precautions:

1 . Always tighten the knob for securing the position of the shelf when in use, or after repositioning.

2. Always place the monitor in the center of the shelf.

3. Ensure that the monitor fits within the raised border of the shelf. If needed, use a larger shelf.

4. Never stack a separate monitor atop the monitor placed on the shelf.

If the Auxiliary Air Probe contacts the infant's skin when the mattress is in the TrendelenburgIReverse Trendelenburg position, erratic air temperature control can result. Always ensure this probe tip does not contact the Infant.

ELECTRICAL PRECAUTIONS

To ensure grounding reliability, connect the AC Power Cord only to a properly grounded 3-wire hospital grade or hospital use outlet. Do not use extension cords. If any doubt exists as to the grounding connection, do not operate the equipment.

An electric shock hazard exists within the Controller when the cover is removed. Servicing should be performed only by qualified personnel.

To prevent equipment damage or accidental power disconnections, DO NOT connect an lncubator Power Cord directly to an ac wall socket when the lncubator is mounted on a VHA Stand. Always provide power to the lncubator using the Power Cord coming directly from the VHA Stand.

Make sure the building power source is compatible with the electrical specifications shown on the rear center column of the VHA Stand or on the Incubator.

EXPLOSION PRECAUTIONS

Do not use in the presence of flammable anesthetics.

Make sure that the oxygen supply to the lncubator is turned off and that the lncubator is disconnected from the oxygen supply when performing cleaning and maintenance procedures; a fire and explosion hazard exists when performing cleaning andlor maintenance procedures in an oxygen-enriched environment.

Keep matches, lighted cigarettes, and all other sources of ignition out of the room in which the lncubator is located. Textiles, oils, and other combustibles are easily ignited and burn with great intensity in air enriched with oxygen.

OXYGEN PRECAUTIONS

Improper use of supplemental oxygen may be associated with serious side effects including blindness, brain damage, and death. The risks vary with each infant. The method, the concentration, and the duration of oxygen administration should be prescribed by the attending physician.

If it is necessary to administer oxygen in an emergency, theattending physician should be notified immediately.

NOTE: See current edition of "Guidelines for Perinatal Care" of the American Academy of Pediatrics1 The American College of Obstetricians and Gynecologists.

The oxygen concentration insplred by an infant does not predictably determine the part~al pressure of oxygen (PO*) In the blood. When deemed advisable by the attending physician, blood p02 should be measured by accepted clin~cal techn~ques.

Oxygen flow rates cannot be used as an accurate indication of oxygen concentrat~ons in an Incubator.

f Oxygen concentrations should be measured with a calibrated oxygen analyzer at intervals directed by yS the attending phys~c~an.

A dirty air intake filter may increase oxygen concentrations and cause carbon dioxide build-up.

SECTION 3 FUNCTIONAL DESCRIPTION

3.1 GENERAL

This section provides a general description of the In- cubator.

3.2 FUNCTIONAL DESCRIPTION

3.2.1 OVERALL

The control of temperature, humidity, and oxygen concentration is achieved by means of the forced air circulation system as shown in Figure 3.1. A controlled amount of room air (approximately 35 Ipm) is drawn through the air intake filter by means of the motor-driven impeller on the controller.

Supplemental oxygen, which may be introduced through the Oxygen Input Valve on the air intake filter cover, displaces a portion of room air to maintain the total gas intake (including oxygen) at 35 Ipm. Since the amount of room air is controlled by the impeller/fiIter characteristics and the amount of oxygen is controlled by the flowmeter setting, predictable oxygen concentrations within the lncubator can be attained. When oxygen flow exceeds 8 Ipm, a valve within the oxygen inlet housing is activated to restrict air intake so that higher oxygen concentration can be achieved without excessive oxygen flow. At 12 Ipm maximum air intake restriction is achieved.

In addition to drawing fresh, filtered air into the Incu- bator, the impeller provides for the internal recircula- tion at a much greater flow than that of the fresh gas inflow. The total flow of fresh plus recirculated air is directed past the air flow sensor and around the heater with a predetermined portion being directed over the humidity reservoir for humidification. When the Access Panel of the Hood is closed, the Air Cur- tain Cover is closed and all the air enters the infant compartment up through the slot at the right end of the main deck as shown in Figure 3.1. After circulat- ing within the infant compartment, the air is then recirculated down through the slot in the left end of the main deck, past the temperature sensing probe which encapsulates the air temperature control thermistor and a high air temperature alarm thermistor, and back to the impeller. When the Access Panel of

( ( the Hood is open, the Air Curtain Cover is raised per- mitting a portion of the air to flow upward past the

opening (Figure 3.1) creating a warm air curtain which minimizes the drop in airtemperature in the In- cubator.

3.2.2 TEMPERATURE CONTROL

The Model C450 QT8 lncubator temperature is regulated using either lncubator air or infant's skin temperature as the controlling parameter; the desired mode is selected by a front panel key. The Model C400 QT8 lncubator provides only Air Mode Control.

In either mode of operation, the heater output is pro- portional to the amount of heat required to maintain the desired temperature, and the relative amount of heat being provided is indicated by the number of lit Heater Power % Indicators on the front panel. Changes in the numberof lamps illuminated indicate the amount of power required to maintain a given temperature. During Baby Mode Control, the Model C450 provides an indication of the degree of the infant's dependency upon the temperature of its environment to maintain body temperature. Each mode of operation is described below.

AIR CONTROL MODE (MODELS C400 QT8 and C450 QT8). In this mode of operation, the air temperature can be maintained from 20.0 to 37.0 "C (20.0 to 38.5 O C Temperature Override Mode ) as indicated by the Set Temp "C Display setting. The In- cubator air temperature is monitored by a probe located below deck and compared with the Set Temp°C Display setting. The information from this probe is supplied to the heater control circuitry which proportions the heater output to maintain lncubator air temperature at the Set Temp "C Display setting. Actual air temperature is displayed by the Air Tem- perature "C Display. A second sensor within the air temperature probe servesas a backup to limit the In- cubator temperature to between 39 "C and 40 OC; at this temperature an alarm is activated, the heater is shut off.

If desired, an auxiliary air temperature probe can be used to control the lncubator air temperature. This probe is suspended above the mattress through the weighing scale hole and plugged into a special receptacle on the side of the Incubator. When plugged


in, the primary air temperature control probe is dis- temperature will be a function of the air temperature connected, but the backup sensorwithin the primary and the infant's ability to establish and maintain its temperature probe remains connected. Thus, the own temperature.

In the Air Mode Control of operation, the infant's

BABY MODE CONTROL (MODEL C450 QT8 Only). In this mode of operation, the infant's skin temperature can be maintained as indicated by the Set Temp "C Display from 34.0 to 37.0 "C (37.0 to 37.9 "C in Temperature Override Mode ). A temperature sensing probe is attached directly to the infant's skin; the information from the probe is supplied to the heater control circuitry which proportions the heater output to maintain the Baby's Temperature at the Set Temp "C setting. Actual baby temperature is displayed by the Baby Temperature "C Display. The Set Temp "C setting does not control air temperature while in Baby Mode Control, but air temperature is still displayed. The air temperature is still limited to 38.5 "C. If the Air Mode Control is selected while the skin probe remains connected, the Baby Temperature "C Display will continue to display actual skin temperature, but will not control.

If the probe is disconnected from its receptacle during Baby Mode Control of operation, the Baby Temperature "C Display blanks and a probe alarm is activated. The High Temp alarm sensor within the Air Temperature probe remains in the circuit to limit

6 the air temperature to less than 40.0 "C.

3.2.3 ALARMS

Alarms are provided for Power Fail, System Fail, inadequate Air Flow, Probe Fail, High Temp and variation from Set Temp. Each time the unit is turned on, the unit is automatically stepped through an alarm check sequence to verify proper alarm function. After the automatic alarm check is made, the low Set Temp alarm is disabled for 60 minutes or until the temperature reaches the Set Temp "C setting, whichever occurs first; each of these alarms is described below.

AIR FLOW. A sensor located below deck in the normal air path of the fan controls this alarm. If air flow stops due to a fan failure, the temperature of the self-heated sensor rises causing the Air Flow alarm lndicator on the front panel to light and produce a pulsating audible tone. A short-circuited air flow sensor failure will also actuate the alarm within 10 seconds of the occurrence of the failure. This alarm is not self-resetting and cannot be silenced and cannot be canceled by the SilenceIReset Key until the alarm condition is corrected.

( HIGH TEMPERATURE. A second sensor within the Air Temperature Probe sounds this alarm if the Incu-

bator temperature reaches 39.5 + 0.5 "C. A High Temp alarm is indicated by aflashing light and acon- tinuous audible tone. This alarm is not self-resetting and cannot be canceled by the SilenceIReset Key until the alarm condition is corrected.

POWER FAILURE. If primary powerto the lncubator is interrupted for any reason, including a disconnected powercord, an audible alarm is activated and the Power Fail lndicator lights. This alarm can be silenced for two minutes by the SilenceIReset Key. This alarm can be deactivated only by restoring the primary power or setting the lncubator POWER Switch off.

SYSTEM FAIL. If an internal malfunction is de- tected, the System Fail lndicator will flash and the audible alarm will sound. This alarm is not resettable and the unit should be referred to qualified service personnel.

PROBE. Circuitry is provided to monitor the air, skin and high temperature sensors for short-circuited, open-circuited, or disconnected conditions and the air flow sensor for open condition.

In the Model C450 QT8 Incubator, a Probe indicator light flashes and an audible alarm sounds within 10 seconds to indicate a defective air temperature, baby temperature or auxiliary air sensor or an open- circuited air flow sensor (see IMPORTANT). The Probe alarm is also activated if the skin temperature probe is disconnected while in the Baby Mode Con- trol.

The Model C400 QTB lncubator is equipped only for air control; therefore, no baby probe alarm is provided. The Probe alarm is activated to indicate a defective air temperature or auxiliary sensor or and open -circuited air flow sensor (see IMPORTANT).

IMPORTANT- The probe alarm will be actuated within 10 seconds if the air flow sensor is open-circuited and the temperature sensed below the mattress deck is greater than approximately 30 "C; however, if the temperature sensed below the mattress deck is less than approximately 30 "C, the alarm will not be activated. During warm-up, it can take anywhere from 15-30 minutes before the alarm actuates, depending on the temperature set point and ambient room


temperature. The probe alarm indicating an open-circuited air flow sensor will not occur if the high Set Temp is below 29 " C.

In either Incubator, if a probe shorts (except for the air flow probe Or high temperature alarm probe), it will also appear as a Set Temp violation, and the Set Temp alarm will light. This alarm is not self-resetting and cannot be canceled by the Alarm SilenceIReset Key until the alarm condition is corrected. If a Probe alarm occurs simultaneously with a Set Temp alarm, a shorted probe is probably the true cause of the alarm, since a shorted probe will appear as a high temperature condition.

SET TEMP. The Set Temp alarm is actuated if baby or air temperature fluctuates from set temperature as follows:

*Baby Temperature +1 .O + 0.3 "C

-1 .O + 0.3 "C

Air Temperature +I .5 f 0.5 "C

-3.0 + 0.5 "C

A temperature below the Set Temp is indicated by a flashing light, an audible tone, and the set temperature setting alternating with LO in the Set Temp 'C Display ; a temperature above the Set Temp is indicated by a flashing light, an audible tone, and the set temperature setting alternating with HI in the Set Temp 'C Display. If a Set Temp alarm occurs simultaneously with a Probe alarm, a shorted probe is probably the true cause of the alarm, since a shorted probe will appear as a high temperature condition.

When silenced, the alarm indicator will remain on until the alarm condition is corrected. If the alarm condition is not corrected within 15 minutes, the audible alarm will be reactivated.

In addition, if it is desired to change the Air or Baby Set Temperature (either High or Low) after the Incu- bator is in operation, the Set Temp HI and LO alarms are automatically silenced for a specific amount of time after the operator raises or lowers the Air or Baby Set Temp from the current operating temperature. The time the alarm remains silent is 5 minutes per degree (plus or minus) change from the current set temperature.

Example: A 1.5 degree ( plus or minus) change from set temperature will generate an alarm silence period of 7.5 minutes.

If the lncubator fails to reach the new set temperature after the specified time, the alarm will sound.

3.2.4 VERTICAL HEIGHT ADJUSTABLE STAND (OPTION, REFER TO FIGURE 1.1)

The Vertical Height Adjustable Stand provides the C400 QT8 and C450 QT8 Incubators with the ca- pability of varying lncubator height over a range of 8 112 inches. The VHA is powered by an electric motor which is controlled by a momentary upldown foot switch. The VHA Stand has its own power cord and provides power to the lncubator which is mounted on it. In addition, if the VHA Stand circuit breakeropens, power will still be provided to the lncubator which is protected by its own circuit breaker.

4.2 OPERATION

The operating procedure is divided into two main sections: General Operation and Functional Check- out Procedure (4.2.1), and Operation During Use (4.2.2). The operational checkout should be performed each time the lncubator is put into service to verify proper operation of all functions. The operation section should be used for subsequent routine operation.

WARNING: The lncubator should not be used if it fails to function as described. Service should be referred to qualified personnel.

4.2.1 GENERAL OPERATION AND FUNC- TIONAL CHECKOUT PROCEDURE

The operational checkout should be performed before the lncubator is first placed into use and after any disassembly for cleaning or maintenance.

A. CHECK FOR LOOSE CASTERS (Standard Cabinet Stand Only) by lifting each end of the

Standard Cabinet Stand. CONNECT THE AC POWER CORD to the VHA Stand ac power outlet when lncubator is mounted on a VHA Stand (Option). The lncubator power cord should be connected to the VHA Stand receptacle to prevent accidental disconnection or damage when the lncubator is raised or lowered.

CAUTION: Make sure that the building power source is compatible with the electrical specifications shown on the right side of the lncubator and VHA Stand. For proper grounding reliability, connect the power cord only to a properly marked 3-wire hospital- grade or hospital-use receptacle. Do not use extension cords.

The following CAUTION should be observed when the lncubator is mounted on a Standard Cabinet Stand.

CAUTION: To minimize the risk of tipping during transport, the Cabinet Stand doors must remain closed during transport.

The following CAUTIONS should be observed when the lncubator is mounted on a VHA Stand.

lncubator approximately 2" and pulling down on each caster. A loose caster may fall out during CAUTION: HEAVY EQUIPMENT - To prevent in-

use if lncubator is lifted over cables, door sills or jury or damage to the Incubator/

elevator thresholds. This could result in Incuba- Stand, when transporting, two per-

tortipping over when lowered to floor. Do not use sons of sufficient strength are re-

FIGURE 4.8 FILTER COVER REMOVAL

P. CHECK AIR CONTROL MODE OF OPERA- TION. With all access openings closed, allow the lncubator to warm up to the Set Temp "C Display setting (33.0 "C); it should take less than one hour. While the unit is warming up, suspend the Auxiliary Probe through the hole in the top of the lncubator Hood and position the patient probe on the center of the mattress surface; do not connect the probe plugs to the receptacles. When the Air Temperature "C Display has stabilized, the number of Heater Power % Indica- tors illuminated will typically be reduced to no more than two. Check that the Air Temperature 'C Display remains within 0.5 "C of Set Temp "C Display for 15 minutes after stabilization.

Q. CHECK AUXILIARY PROBE. Insert the Auxil- iary Probe connector into the AUXILIARY AIR

'

PROBE receptacle. When the Air Temperature OC Display has stabilized, the number of Heater Power % Indicators illuminated will typically be reduced to no more than two. Check that the Air Temperature 'C Display remains within 0.5 'C of ~ e t ~ e m p OC Display for 15 minutes after stabilization.

R. CHECK BABY MODE CONTROL* OF OP- ERATION. Connect the Patient Probe plug to the PATIENT PROBE Receptacle and select Baby Mode Control. Set the Set Temp 'C Dis- play to 36.0 OC. Locate the sensor to control air temperature above center mattress. If the Set Temp alarm actuates, depress the SilenceIRe- set Key.

S. CHECK BABY SET TEMP ALARM.* Allow In- cubator Temperature to stabilize at 36 "C. Re- move the PATIENT PROBE sensor from the In- cubator. In approximately 15 seconds Set Temp LO alarm should occur.

T. CHECK PATIENT PROBE ALARM.* Discon- nect the Patient Probe from the receptacle. The audible and visual alarms should activate, the Baby Temperature "C Display should blank, and the Heater Power % Indicators should all go off. When the Patient Probe is reconnected, the lncubator should return to normal operation after the SilenceIReset Key pressed.

U. CHECK AIR FLOW ALARM. Set the POWER switch to off. Remove the Controller (Figure 5.1) from the Incubator. Remove the fan impeller from the fan motor shaft, and reinstall the Con- troller in the Incubator. Set the POWER switch to on and wait for the end of the Auto-Test cycle (5 seconds). Within 5 minutes, the Air Flow indicator should flash, a pulsating audible alarm should sound, and all Heater Power % Indica- tors should go out. Reinstall the fan impellerand restore the lncubator to normal operating condition before proceeding.

V. CHECK HIGH TEMPERATURE ALARM. Se- lect Air Mode and set the Set Temp "C Display to 36 OC. Position probe end of auxiliary probe outside the Incubator. With the Keypad locked, simultaneously press and hold the >37 "C Key and the Up Arrow Key for 3 seconds. The Baby Temperature "C Display should show [ . ] and the Air Temperature OC Display should show the current lncubator temperature and begin to rise.

If the Set Temp Alarm actuates, press the Si- IenceIReset Key. When lncubator temperature reaches 39.5 + 0.5 "C (USA lncubators only. All other lncubators will alarm at 37.5 + 0.5 "C) , the High Temp Indicator should come on and the audible alarm should sound.

Press the Keypad Lock key to exit the High Tem- perature test mode. Return the auxiliary probe to inside the Incubator. When the Incubator temperature falls below 39.0 "C (USA lncubators only. All other lncubators 37.0 "C), press the Si- IenceIReset Key to cancel the High Temp Alarm.

W. CHECKTHE OXYGEN INPUT VALVE FILTER. The Oxygen Input Valve Filter Cartridge should be checked once every four months and replaced if the ends are gray or black. Refer to the Service Manual and qualified service personnel.

X. CHECKOUT IS COMPLETE. Disconnect and store the Auxiliary and Patient Probes. If the In- cubator is to be used, place it in Air Mode Con- trol and leave the lncubator running until ready for use. If it is not going to be used, it may be shut off.

4.2.2 OPERATION DURING USE

IMPORTANT- The lncubator should not be placed in service unless the General Opera- tion and Functional Checkout Proce- dure (4.2.1) has been performed.

The lncubator should be ventilated and pre-warmed in the Air Mode Control to the temperature prescribed by the attending physician or according to Nursery Standing Orders. The lncubator should be

run with no water in the humidity reservoir during pre-warming.

NOTE: The aircurtain which functions when the Ac- cess Panel is open can be disturbed by drafts, fans, air-conditioning, etc. Take necessary measures to keep the lncubator a way from these drafts.

A. PLACE INFANT IN INCUBATOR through opened Access Panel. Mattress Tray should be pulled out to stop as shown in Figure 4.7. Return Mattress Tray to normal use position and close Access Panel.

C

WARNING: Both Access Panel Latches must be positively secured to avoid accidental opening.

The use of infant seats, head hoods or other equipment or supplies within the In- cubator which can alter the air flow pattern may affect temperature uniformity, temperature variability, the correlation of the lncubator temperature reading to center mattress temperature and infant skin temperature. To prevent infant fall when Access Door is open:

DO NOT leave lnfant unattended. DO NOT raise the hood when the mattress is elevated. DO NOT force mattress tray when pulling it out. Dislodgment of the tray from the support rails on the lncubator hood baffles can occur.

B. SELECT TEMPERATURE MODE CONTROL (AIR OR BABY)

IMPORTANT- The temperature CONTROL MODE and temperature settings should be prescribed by the attending physician. infant's rectal and/or axillary temperature should be routinely monitored according to the attending physician's orders or Nursery Stand- ing Orders.


WARNING: For infant safety, do not leave the infant unattended while the Access Panel is open. The lncubator temperature may rise above the Set Temp "C setting if the Ac- cess panel is left open. Do not leave it open longer than essential. The Air Tem- perature "C Display does not accurately reflect INCUBATOR TEMPERATURE when the Access Panel is open. When the Access Panel is opened, a curtain of warm air flows from beneath the front edge of the mattress toward the top of the Access Panel opening. The temperature of this air curtain is higher than the typical lncubator air temperature, therefore, the infant should be kept clear of this warm air path. Do not place surgical covers or blankets over the infant and warm air curtain or side vents simultaneously. This may cause heat induced injury and burns. Raising the Hood or tilting the Mattress Tray, if leads or tubing are connected to the infant, could result in harm to the infant if the mattress is tilted. There should be no need to raise the hood at any time while the infant is cared for in the Incu- bator. All necessary access to the infant can be achieved by means of the Access Panel, Access Doors, and Iris Entry Ports. Phototherapy units located too close to the lncubator may affect Hood wall temperature, INCUBATOR TEMPERATURE and infant skin temperature.

If using a VHA Stand, phototherapy lamps placed over top of the lncubator hood can interfere with elevator positioning and monitor shelf placement. To prevent this interference, always remove the phototherapy lamp prior to repositioning the elevator. Always lower the lncubator to its lowest position prior to transport for optimum stability and remove monitors from the swivel shelves.

AIR MODE CONTROL. Select Air Mode Con- trol. Use the UpIDown '~ r rows to set the Set Temp "C Display to the prescribed temperature. Once stabilized, the lncubator temperature will be maintained within 0.5 "C of Set Temp "C. Note the following:

NOTE: The Set Temp LO alarm is silenced for up to 60 minutes after the lncubator is turned on or until the selected Set Tem- perature is reached.

If it is desired to change the set temperature (either high or low) after the lncubator is in operation, the Set Temp LO and HI alarms are automatically silenced for a specific amount of time after the operator raises or lowers the set temperature from the current set temperature. The time the alarm remains silent is 5 minutes per degree (plus or minus) from the current Incu- bator temperature.

Example: A 1.5 degree (plus or minus) change from set temperature will generate an alarm silence period of 7.5 minutes.

If the lncubator fails to reach the new set temperature a f t ~ r the specified time, the alarm will sound.

The number of Heater Power % Lights illuminated provides an indication of the amount of heater output required to maintain the lncubator air temperature.

The Air Temperature "C Display indicates IN- CUBATOR TEMPERATURE.

If the Patient Probe is connected to the PA- TIENT PROBE Receptacle, the Baby Temper- ature "C Display (Model C450 only) will indicate but not control baby temperature; otherwise, this display will be blank.

Auxiliary Air Probe. If desired, the Auxiliary Air Probe can be used in thBAir Mode Control to control the lncubator temperature rather than the probe below the main deck. The High Temp Alarm and the Air Temperature "C Display still use the probe below deck.

Insert the probe end through the hole on the top of the Hood. Make sure the probe hangs freely inside the Incubator. To use the probe, insert its


plug into the AUXILIARY AIR PROBE receptacle.

WARNING: For proper temperature control, the Auxil- iary Air Probe must be directly beneath the hole in the Hood. Do not operate the In-

cubator with the Auxiliary Air Probe outside the lncubator or other than as recommended. Overheating will occur.

CAUTION: I f the Auxiliary Air Probe contacts the Infant's skin when the mattress is in the Trendelenburg/Re- verse Trendelenburg position, erratic air temperature control can result. Always ensure that the probe tip does not contact the infant.

BABY MODE CONTROL. Connect the plug of the Skin Temperature Probe to the PATIENT PROBE Receptacle. Insert the probe into the hood compartment through the right Tubing Ac- cess Grommet as shown in Figure 4.9.

NOTE: The Set Temp LO alarm is silenced for up to 60 minutes after the lncubator is turned on or until the selected Set Tem- perature is reached.

If it is desired to change the set temperature (either high or low) after the lncubator is in operation, the Set Temp LO and HI alarms are automatically silenced for a specific amount of time after the operator raises or lowers the set temperature from the current set temperature. The time the alarm remains silent is 5 minutes per degree (plus or minus) from the current Incu- bator temperature.

Example: A 1.5 degree (plus or minus) change from set temperature will generate an alarm silence period of 7.5 minutes.

If the lncubator fails to reach the new set temperature after the specified time, the alarm will sound.

FIGURE 4.9 TUBING ACCESS GROMMET

The skin area where the probe is to be placed should be thoroughly cleaned and dried before the probe is placed on the skin. When the infant is on its back or side, the Probe should be placed on the abdomen, halfway between the xyphoid and the umbilicus. When the infant is prone, the probe should be on the infant's back. The probe must never be placed under the infant or used rectally.

Attach the probe to the infant using an Air- Shields Critter Covers@ Probe Cover, as shown in Figure 4.10. To stabilize the attached probe, place a piece of tape over the probe wire approximately three to four centimeters from the probe tip.

Select Baby Mode Control. Use the UpIDown Arrows to set the Set Temp "C Display to the desired temperature. Once stabilized, the infant probe temperature will be automatically controlled within 0.3 "C of the Set Temp "C Display as indicated by the Baby Temperature "C Dis-

play.

Attach Probe

FIGURE 4.10 ATTACHING SKIN PROBE


WARNING: When administering oxygen therapy by means other than the rear panel Oxygen In- put Valve, the oxygen concentrations guide values identified in Figure 4.12 will not be valid. The Oxygen concentrations should always be independently measured to verify delivery of the prescribed oxygen concentration.

Improper use of supplemental oxygen can cause serious side effects including blindness, brain damage and death. The risks vary with each infant. The method, the concent'ration and the duration of oxygen administration should be prescribed by the attending physician. If i t is necessary to administer oxygen in an emergency, the attending physician should be notified immediately.

The oxygen concentration inspired by an infant does not predictably determine the partial pressure of oxygen (p02) in the blood. When deemed advisable by the attending physician, blood p02 should be measured by accepted clinical techniques. The use of the Dew-etteB 2 lncubator Humidifier or other means of external humidification will alter predicted lncubator oxygen concentrations. Refer to Cat. No. 68 996 35 for operating Instructions for the Dew-ette@ 2 lncubator Humidifier.

ISOLETTE@ Infant lncubator ,,

When the temperature inside the lncubator is significantly higher than the temperature in the nursery, condensation may form on the inside of the hood. When there is rela- tively little temperature difference between the lncubator and the nursery, condensation willnot form. This does not mean the In- cubator air is not adequately humidified but rather that the difference in temperature is not great enough to produce condensation.

A relative humidity readout is provided on a disposable humidity card mounted in the upper right rear corner of the lncubator hood. The card should be changed each time the lncubator is cleaned and/or after each usage.

IMPORTANE

To minimize contamination in the humidity reservoir, it should be completely drained and refilled daily.

Use only sterile distilled water.

Never refill a partially filled humidity reservoir; always drain completely before refilling.

E. WEIGHING THE INFANT

Sling Scale A sling type weighing scale is available as an accessory for the Incubator. If used, a weighing sling is suspended from the scale through the hole in the top of the hood.

NOTE: The scale is set below zero at the factory to compensate for the weight of the hook and sling. If resetting is ever required, place a known weight in the sling and turn the adjustment screw (located in the yoke of the scales) until the correct weight shows on the scale. Do not attempt resetting without a known weight as the empty sling is not heavy enough to give an accurate zero point.

New disposable elements should be installed after sterilization.

Release the Controller latches and slide the unit out about 114". The Access Panel may be closed, but the Access Doors should be left open. The Air Intake Microfilter may be left in place.

CAUTION: Sterilization temperature should not exceed 130 " F (54.5 "C).

NOTE: Gas sterilization does not eliminate the need for routine replacement of the Air In- take Microfilter.

Standard Gas sterilization procedures as pro- grammed by automatic equipment such as made by American Sterilizer and Wilmot Castle are satisfac- tory as these do not normally exceed 130 O F (54.5 "C).

Upon completion of gas sterilization, an aeration period of 16 to 24 hours should be allowed. The Con- troller should be properly secured in place and the lncubator should be operated in a dry condition for the entire period of aeration at a temperature of 32 to 35 "C. After aeration, if the unit is not to be used immediately, a disposable dust cover should be placed on the lncubator.

IMPORTANT: A complete Functional Checkout Pro- cedure (paragraph 4.2.1) should be performed before return~ng the unit to service. &.
