1. OVERVIEW
The AIRVO 2 is a humidifier with integrated flow generator that delivers high flow warmed and humidified
respiratory gases to spontaneously breathing patients through a variety of patient interfaces.
INTENDED USE
The AIRVO 2 is for the treatment of spontaneously breathing patients who would benefit from receiving
high flow warmed and humidified respiratory gases. This includes patients who have had upper airways
bypassed. The flow may be from 2 - 60L/min depending on the patient interface. The AIRVO 2 is for patients
in hospitals and long-term care facilities.
The AIRVO 2 provides respiratory support through a nasal cannula interface, promoting slower, deeper
breathing and increasing alveolar ventilation. To patients with either nasal cannula or tracheostomy interfaces,
the AIRVO 2 provides airway hydration and may be used with supplemental oxygen, as required.
WARNINGS
!
• The unit is not intended for life support.
• Appropriate patient monitoring must be used at all times. Loss of therapy will occur if power is lost.
• Nasal delivery of respiratory gases generates flow-dependent positive airway pressure (PAP). This must
be taken into account where PAP could have adverse effects on a patient.
To avoid burns:
• The unit should only be used with interfaces, water chambers and breathing tubes specified in this user
manual.
• Using the breathing tube or interface for longer than the specified time can result in serious injury
including infection.
• Before using oxygen with the unit, read all warnings in the "Oxygen" section of this manual.
• Never operate the unit if:
• the heated breathing tube has been damaged with holes, tears or kinks,
• it is not working properly,
• the case screws have ever been loosened.
• Do not block the flow of the air through the unit and breathing tube.
• The unit should be located in a position where ventilation around the unit is not restricted.
• Never block the air openings of the unit or place it on a soft surface such as a bed or couch/sofa, where
the filter area may be blocked. Keep the air openings free of lint, hair etc.
To avoid electric shock:
• Do not store or use the unit where it can fall or be pulled into water. If water has entered the unit enclosure,
disconnect the power cord and discontinue use.
• Never operate the unit if:
• it has been dropped or damaged,
• it has a damaged power cord or plug,
• it has been dropped into water.
• Avoid unnecessary removal of the power cord from the rear of the device. If removal is necessary, hold the
connector during removal. Avoid pulling on the power cord.
• Return the unit to an authorized service center for examination and repair, except as outlined in this
manual.
To avoid choking, or inhalation of a foreign object:
• Ensure an air filter is fitted when operating your unit.
• Never drop or insert any object into any opening or tube.
Miscellaneous:
• Humidity output will be compromised below 18°C (64°F) and above 28°C (82°F).
• The unit is not suitable for use in the presence of a flammable, anesthetic mixture with air or oxygen or
nitrous oxide.
• Prior to each patient use, ensure that the auditory alarm signal is audible by conducting the alarm system
functionality check described in the Alarms section.
