MACS CPAP System

Self Guided Tour

Program Objectives

This program is a self guided tour of the

MACS CPAP System.

At the end of this tour you will be able to:

Describe the main operating features of MACS Identify the controls and connections Describe the patient circuit Set-up MACS for patient operation Define various clinical environments for CPAP application Clean and maintain the MACS

Features and Controls – Rear Panel

Driving Gas Input

Connection for 50 psi oxygen source gas

Always use a high flow gas source (pressure take-off) that can provide 55 + 15 psi pressure at a minimum of 40 L/min

Features and Controls – Rear Panel

Air Entrainment

Ambient air is entrained for internal gas mixing

External housing contains air filter

Air filter replacement is part of the preventative maintenance

Features and Controls – Front Panel

CPAP Control

Adjusts the CPAP from 0 to 20 cm H2O

Automatic sensitivity Flow adjusts automatically

to meet patient demand up to 140 L/min

Oxygen concentration is maintained at set % Oxygen control

Features and Controls – Front Panel

% Oxygen Control

Delivered oxygen choice 65% 100%

Sets the spontaneous breath oxygen concentration

Features and Controls – Front Panel

Pressure Gauge

Shows pressure in patient circuit at the output of MACS

Gives an indication of patient effort

Features and Controls – Front Panel

Circuit Connection 1

Connection for the large bore hose of the patient circuit

Features and Controls – Front Panel

Circuit Connection 2

Patient circuit small hose connection

Connects to the expiratory valve on the patient circuit

Patient Circuit

Patient circuit is a disposable, single limb system; Both hoses attach to the front of MACS Patient end connects for clinical intervention

Directly to an endotracheal tube (invasive) Resuscitator face mask (noninvasive)

Use 90 degree elbow to connect bacteria filter for operator protection

Patient Circuit

Use only Airon Corporation patient circuits; Calibration of the CPAP control is based upon the Airon

patient circuit Using other manufacturers circuits may cause

errors in pressure delivery high expiratory flow resistance interference with CPAP sensitivity increased oxygen usage

Program Objectives

MACS CPAP System self guided tour, objectives completed so far:

Describe the main operating features of MACS Identify the controls and connections Describe the patient circuit

With an understanding of MACS’s capabilities, let’s look at patient application.

Patient Application

Initial Set-up Attach Airon patient circuit

to MACS Attach a high pressure

oxygen hose to the rear of MACS

Attach this hose to the oxygen source

Patient Application

Set % Oxygen Control Set % Oxygen control to the desired

oxygen level All breaths receive set oxygen level

+ 10% Oxygen tank time doubles with 65% Caution - with rapid, large tidal

volumes on 100% oxygen, the actual delivered percentage might be slightly less than 100%

Patient Application

Start CPAP Turn on oxygen source Attach patient breathing

circuit to the patient using either a mask or endotracheal tube

Adjust the CPAP control to the level desired

If the patient is not attached to the circuit, or there is a large leak, a high flow of gas will occur

Patient Application

Monitor patient Assess per your protocol

patient breathing rate comfort oxygenation CO2

Clinical Issues

Pediatric Support

MACS is safe for pediatric - adult patients

Use the lowest possible settings Monitor closely for patient synchrony

Clinical Issues

Providing nebulized medications

A medication nebulizer may be placed between the patient connection and the patient

Patient will inhale medication during every breath and exhale back out through patient circuit

Filters may be added for personnel safety

Clinical Issues

CO2 Monitoring

Any type of CO2 analyzer may be used

Inline style analyzers should be place between the patient circuit connection and the patient

Place the sampling tube of sidestream analyzers under the patient mask

Clinical Issues

Altitude Operation

MACS can be used for air transports in unpressurized cabins up to 15,000 feet

Pressure settings will not change as altitude changes

Patient Safety

Patient Safety Features

Internal Safety Pressure Release – limits circuit pressure to 40 cm H2O

Anti-Suffocation System – in the event of device malfunction, an internal valve will allow ambient air to enter the patient circuit

Cleaning and Maintenance

Clean MACS between patients using a soft cloth and a mild detergent / disinfectant

Do not immerse MACS in water Patient circuit is disposable, single use

application and should not be cleaned, disinfected or reused

MACS should receive preventative maintenance every 2 years

Program Objectives

MACS CPAP System self guided tourcompleted; you should now be able to:

Describe the main operating features of MACS Identify the controls and connections Describe the patient circuit Set-up MACS for patient operation Define various clinical environments for CPAP application Clean and maintain MACS

Next Step – consider reviewing the MACS Case Study and completing the competency evaluation
