2. SETTING UP AIRVO 2 FOR FIRST USE

1. REMOVE THE AIRVO 2 FROM ITS PACKAGING

Place the AIRVO 2 on the 900PT405 pole mounting tray, on the 900PT421 hospital stand.

2. CONNECT THE POWER CORD

Plug the power cord connector into the socket on the back of the AIRVO 2.

3. ATTACH THE OXYGEN INLET EXTENSION KIT

Refer to the instruction sheet included with the kit itself.

4. ATTACH WATER CHAMBER AND HEATED BREATHING TUBE

The water chamber and heated breathing tube must be connected to carry out the following setup and testing procedures.

If you have not been supplied with a reusable HC360 water chamber, you can use an MR290 chamber instead.

5. SWITCH ON UNIT

Switch on the unit by pressing the On/O button.

6. WARM-UP

The unit will begin to warm up.

ENVIRONMENT SETTINGS (FOR DEFAULT MODE)

A clinician may change the “Environment Settings”, to customise individual AIRVOs for dierent environments (eg. intensive care, general care areas, emergency departments). The “Environment Settings” chosen will put limits on the “Patient Settings” that the operator can choose when in normal use.

This screen deﬁnes the “Environment Settings” for the AIRVO 2 when in Default Mode (ie. non-“Junior Mode”).

Minimum ﬂow (L/min) The lowest ﬂow that the operator will be able to

Maximum ﬂow (L/min) The highest ﬂow that the operator will be able

Maximum oxygen fraction (%) The highest oxygen fraction that the operator

Minimum oxygen fraction (%) The lowest oxygen fraction that the operator

Note that, for Oxygen display, this is a measurement only, not a control setting. The operator changes the measured oxygen fraction by altering the AIRVO 2 target ﬂow setting and the ﬂow of oxygen connected to the unit (e.g. from a ﬂowmeter)

The lowest target dew-point temperature that the operator will be able to select.

Possible Settings: 31, 34, 37 °C If this is set to 31, the operator can select a target dew-point temperature between 31 and 37. ie. 31, 34 or 37 (°C). If the patient is tracheostomised, a clinician may wish to set this value to 37, so that the operator can only select a target dew-point temperature between 37 and 37, ie. only 37 (°C). Note: The maximum dew-point temperature setting is always 37 °C in Default Mode.

Possible Settings: 10 to 60 in increments of 5 L/min, always less than or equal to Maximum Flow setting.

Example: If this is set to 10, the operator will be able to select ﬂows down to 10 L/min. If this is set to 25, the operator will be able to select ﬂows down to 25 L/min.

Possible settings: 30 - 100% in increments of 5% O2.

The unit will alarm if the measured oxygen fraction exceeds this value. Note: Even if this ‘Maximum oxygen fraction‘ setting is set to 100%, any time the measured oxygen fraction exceeds 95%, the oxygen reading will pulse red and the device will beep.

Possible settings: 21 or 25% O2.

When set to 25% the unit will alarm if the measured oxygen fraction is below this value. This allows detection of oxygen being disconnected.

To change the environment settings:

Hold the Up and Down buttons for 3 seconds to “unlock” the ﬁrst setting.

Use the Up and Down buttons to change the setting, then press the Mode button to progress to the next setting.

Press the Mode button to conﬁrm the change and/or move on to the next screen.
