Fisher & Paykel AIRVO™ 2 User Manual
This manual is intended for healthcare professionals and applies to AIRVO 2 units with LOT numbers 130621 and above.
1. Overview
The AIRVO 2 is a humidifier with an integrated flow generator that delivers high-flow warmed and humidified respiratory gases to spontaneously breathing patients through various patient interfaces. It is designed for patients in hospitals and long-term care facilities.
Intended Use
The AIRVO 2 is for the treatment of spontaneously breathing patients who benefit from receiving high-flow warmed and humidified respiratory gases, including those with bypassed upper airways. The flow rate can range from 2 to 60 L/min, depending on the patient interface.
Warnings
- Nasal delivery of respiratory gases generates flow-dependent positive airway pressure (PAP).
- The unit is not intended for life support.
- To avoid burns: Use only specified interfaces, water chambers, and breathing tubes. Prolonged use of the breathing tube or interface may cause serious injury. Read warnings in the "Oxygen" section before using oxygen. Never operate the unit if the heated breathing tube is damaged, if it is not working properly, or if case screws have been loosened. Do not block airflow. Ensure adequate ventilation around the unit and avoid placing it on soft surfaces that could block air openings. Keep air openings clear of lint and hair.
- To avoid electric shock: Do not store or use the unit where it can fall into water. If water enters the unit enclosure, disconnect the power cord and discontinue use. Never operate if the unit has been dropped, damaged, has a damaged power cord, or has been dropped into water. Avoid unnecessary removal of the power cord; hold the connector when removing. Return the unit to an authorized service center for examination and repair.
- To avoid choking or inhalation of a foreign object: Ensure an air filter is fitted. Never drop or insert objects into any opening or tube.
- Miscellaneous: Do not use the unit if the room temperature is outside 10°C - 30°C (50°F - 86°F). Humidity output may be compromised below 18°C (64°F) and above 28°C (82°F). The unit is not suitable for use with flammable anesthetic mixtures with air or oxygen or nitrous oxide.
2. Setting up AIRVO 2
Before You Begin
The AIRVO 2 should be fixed on a pole mounting tray (900PT405) below patient head height. Open the packaging of the tube & chamber kit.
Install Water Chamber
Remove blue port caps, fit the supplied adapter over the chamber's vertical ports, and attach the water supply tube. Fit the water chamber to the unit by aligning it with the blue chamber port and pushing firmly until it clicks.
Warnings: Do not start the unit without the water chamber. The water becomes hot during use; exercise caution when removing/emptying. Do not touch the heater plate, chamber, or base during use. Avoid tilting the machine to prevent water entering the unit. Empty the water chamber before transporting.
Cautions: For optimal therapy (MR290 only), do not use the auto-fill MR290 chamber if dropped or run dry with the "water out" alarm activated.
Connect Water Bag
Attach the sterile water bag to the hanging bracket above the unit. Insert the bag spike into the fitting at the bottom of the bag and open the vent cap. The chamber will automatically fill and maintain the water level. Ensure the chamber and/or water bag do not run out of water.
MR290 Flow setting vs usage time (2-litre sterile water bag):
| L/min | 2 | 5 | 10 | 15 | 20 | 25 | 30 | 35 | 40 | 45 | 50 | 55 | 60 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| hrs | 379 | 152 | 76 | 51 | 38 | 30 | 25 | 22 | 19 | 17 | 15 | 14 | 13 |
3. Using AIRVO 2
Switch On Unit
Plug the power cord into the mains supply, ensuring the connector is secure. Ensure the unit is dry before plugging in. Switch on using the On/Off button.
Check Disinfection Status
The unit displays whether it is safe for use on a new patient based on its last disinfection.
Warm-up
The unit warms up, displaying current dew-point temperature, flow, and oxygen values. These values pulse until they reach target settings. This is the "Summary screen".
Junior Mode
For Optiflow Junior nasal cannulas (OPT316/OPT318), activate Junior Mode by holding the Mode button for 5 seconds. This limits target settings to 34°C and 2-25 L/min. The screen icons indicate Junior Mode. Hold the Mode button for 5 seconds to deactivate.
Configure Target Settings
Press the Mode button to view target settings (locked by default).
Target Dew-Point Temperature
Settings: 37°C (98.6°F), 34°C (93°F) [for compliance issues], 31°C (88°F) [for face masks only]. Settings may be limited based on configuration. The unit returns to 37°C after disinfection.
To change: Hold Up/Down buttons for 3 seconds to unlock. Use Up/Down to select, then press Mode to lock.
Transport Mode
Activate by holding the "Audio pause" button for 5 seconds. Enters a low-power, low-humidity mode for 20 minutes for patient transport. Deactivate by holding the "Audio pause" button for 5 seconds.
Target Flow
Settings: 10-60 L/min (increments of 1 L/min for 10-25 L/min, 5 L/min for 25-60 L/min). Settings may be limited. The unit remembers the last flow setting.
To change: Follow the same steps as for changing dew-point temperature.
Note: Low ambient temperatures may prevent reaching 37°C at high flow settings. Consider decreasing the target flow.
Connect Your Patient
Wait for the "Ready for use" symbol on the Summary screen. Connect the patient interface to the heated breathing tube. Monitor flow and oxygen values, adjusting oxygen as needed. The air will feel warm initially.
During Use
A screensaver activates after 1 minute of inactivity. If excess condensate forms in the heated breathing tube, drain it into the water chamber.
After Use
Switch off the unit by pressing the On/Off button.
4. Reprocessing
The AIRVO 2 must be cleaned and disinfected between patients per the Disinfection Kit Manual (900PT600). Follow aseptic techniques to minimize contamination. Dispose of consumables properly.
Schedule for Changing Accessories
