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.

This button combination is for use by clinical engineering / technical personnel only.
AIRVO 2 / myAIRVO 2 MODE
You can change the unit from “AIRVO” (hospital) mode to “myAIRVO” (home / long-term care) mode, eg. for patients going home.

Hold the Up and Down buttons for 3 seconds to “unlock” the setting.
Use the Up button to select myAIRVO 2.
Press the Mode button to confirm the change and/or move on to the next screen. Note that the unit will reset itself if it is switched between AIRVO 2 and myAIRVO 2 modes.

ENVIRONMENT SETTINGS (FOR DEFAULT MODE)
A clinician may change the “Environment Settings”, to customise individual AIRVOs for different environments (eg. intensive care, general care areas, emergency departments). The “Environment Settings”
95chosen 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 dew-point |
The lowest target dew-point temperature that |
temperature (°C) |
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. |
Minimum flow (L/min) |
The lowest flow that the operator will be able to |
|
select. |
|
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. |
Maximum flow (L/min) |
The highest flow that the operator will be able |
|
to select. |
|
Possible Settings: 10 to 60 in increments of 5 L/min, |
|
always greater than or equal to Minimum Flow setting. |
|
Example: If this is set to 60, the operator can |
|
select flows up to 60 L/min. |
|
If this is set to 35, the operator can select flows up |
|
to 35 L/min. |
Maximum oxygen fraction (%) The highest oxygen fraction that the operator
95may set the unit to.
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.
Minimum oxygen fraction (%) The lowest oxygen fraction that the operator may set the unit to.
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.
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) - there is no closed-loop control.
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,
95then 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. |

|
|
|

|
|
|
|
|
|
If this is set to 15, the operator can select flows up |
|
|
|
|
|
|
to 15 L/min. |
|
|
|
|
|
|
|
|
|
Maximum oxygen fraction (%) |

|
|
|
|
|
|
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 |
|
|

|
|
|
|
|
|
|
Minimum oxygen fraction (%) |
|
The lowest oxygen fraction that the operator |
||
|
|
|
|
|
|
may set the unit to. |
|
|
|
|
|
|
Possible settings: 21 or 25% O2. |
|
|
|
|
|
|
When set to 25% the unit will alarm if the |
|
|
|
|
|
|
measured oxygen fraction is below this value. This |
|
|
|
|
|

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) |
