2.5 Disposables
The MaxVenturi is intended for use with approved disposables. Several patient
delivery circuits and patient interfaces have been tested and approved for use with the
MaxVenturi. The approved delivery circuits and patient interfaces are:
2.5.1 Disposable Patient Circuits:
• Fisher & Paykel single heated limb circuit (RT202) with humidifier chamber (MR290).
• Airlife single heated limb circuit (RT600-850) with humidifier chamber (MR290).
• Hudson Concha single heated limb circuit 9780-19), with Concha chamber (382-70).
• Standard 6', 22mm corrugated tube (Airlife 001450 or similar. Not humidified).
2.5.2 Disposable Patient Interfaces:
• Optiflow large nasal cannula (Fisher & Paykel OPT544).
• Optiflow medium nasal cannula (Fisher & Paykel OPT546).
• Optiflow Trachaeostomy direct connection (Fisher & Paykel OPT570).
• Pediatric aerosol mask with 22mm inlet (Airlife 001263 or similar).
• Adult aerosol mask (Airlife 001206 or similar).
• Trach adaptor T-piece (Airlife 001500 or similar).
• Superdome oxygen hood (Maxtec R300P06).
• Disposa-Hood oxygen hood (Utah Medical 5119).
• Trachaeostomy mask with 22mm inlet - loose fitting (Airlife 001225 or similar).
Caution: Use of patient circuits or patient interfaces other than these constitutes "off-
label use". This can result in device malfunction or harm to the patient.
Warning: Adjusting the oxygen setting too high at low flows may cause oxygen to exit the
air inlet port. Verify the direction of flow by placing your hand under the air filter to feel
for air escape.
