Cannula Sizes Cannula Flow Range Tip OD

Pediatric Small Up to 20 L/min 1.9 mm

Pediatric/Adult Small Up to 40 L/min 2.7 mm

Adult Large Up to 40 L/min 4.8 mm

FITTING THE CANNULA:

Vapotherm offers 8 different size cannulae to effectively fit patients. Not shown are the intermediate infant, infant, SOLO, neonatal, and premature. These cannulae are designed for neonatal patients. Only Vapotherm cannula should be used with the Vapotherm Precision Flow.

CANNULA APPLICATION:

• Select the appropriate cannula based on the above chart

• Allow the system to reach desired temperature (temperature display will stop flashing) before connecting the delivery tube to the cannula

• The Precision Flow’s operational flow range is locked at 5-40 L/min for the High Flow Disposable Patient Circuit (blue packaging)

Note: There is a low flow disposable patient circuit available specifically for neonatal applications.

Cannula Selection & Application

• Cannulae should be sized not to occlude greater than 50% of the nares

• Cannula prongs should be spread enough not to pinch the nasal septum (erosion risk)

CONDITIONS:

These symptoms are indicative of but not solely attributed to:

• Asthma• Pneumonia• Bronchitis• Bronchiolitis• Influenza

ED Frequently Asked Questions

WHAT IS VAPOTHERM HIGH VELOCITY NASAL INSUFFLATION (HI-VNITM)?High Velocity Nasal Insufflation (Hi-VNI) is a refined form of High Flow Nasal Cannula (HFNC) that uses a small-bore nasal cannula to effectively washout expiratory gas from the extra-thoracic dead space. Hi-VNI not only facilitates oxygenation but also augments alveolar ventilation. Hi-VNI reduces work of breathing (WOB) by providing high flows and high velocities of heated and humidified breathing gas through a simple nasal cannula. Patients experience rapid symptom relief, and mask-free delivery improves patient comfort and simplifies nursing care.WHAT PATIENTS ARE CANDIDATES FOR HI-VNI IN THE ED?Hi-VNI treats symptoms of respiratory distress and is appropriate for patients experiencing high work of breathing, air hunger, hypoxemia and hypercapnia. Patients must be spontaneously breathing, alert and oriented and have the ability to protect their airway. Hi-VNI has been used to effectively support patients with a primary diagnosis of CHF, COPD, asthma, pneumonia, emphysema, bronchitis, bronchiolitis, influenza, chronic pulmonary diseases and general dyspnea. Hi-VNI should not be used in situations where humidification is contraindicated, or with patients that have occluded or defective nares.HOW QUICKLY DOES HI-VNI STABILIZE PATIENTS?Patients often experience rapid symptom relief showing a decrease in respiration rate and work of breathing within minutes of applying the therapy. Anecdotally, you know if a patient will be a responder within the first 10-15 minutes. CAN I USE HI-VNI IN PLACE OF OTHER FORMS OF NONINVASIVE POSITIVE PRESSURE VENTILATION (NIPPV)?Like NIPPV, Hi-VNI can be used effectively as a first line therapy for respiratory support to reduce the need for mechanical ventilation in spontaneously breathing patients. Patients that require pressure to stent the airway are more appropriately treated with NIPPV.HOW EASILY DO PATIENTS TOLERATE HI-VNI?Hi-VNI is generally well tolerated and requires no special fitting of masks or patient education. The optimal heating and humidification of the breathing gas makes even very high flow rates comfortable. The nasal cannula delivery allows patients to speak, drink, take oral medications, and participate in their care.DO PATIENTS NEED TO GO TO THE ICU ONCE PLACED ON HI-VNI?Hi-VNI can be delivered outside of the ICU as long as there is availability of oxygen, compressed air and oximetry monitoring for the patient. Weaning Hi-VNI is simple, and many patients are weaned off of therapy in the ED once medications have had time to impact the root cause of the respiratory distress allowing admission to a unit with a lower intensity of care.
