ENVIRONMENT SETTINGS (FOR DEFAULT MODE)
A clinician may change the “Environment Settings”, to customise
individual myAIRVOs for dierent patients depending on their needs.
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 myAIRVO 2
when in Default Mode (ie. non-“Junior Mode”).
Minimum dew-point
temperature (°C)
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.
Minimum flow (L/min) The lowest flow that the operator will be able to
select.
Possible Settings: 10 to 60 in increments of 5 or 1 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 or 1 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
may set the unit to.
Possible settings: 30 - 90% in increments of 5% O2.
The unit will alarm if the measured oxygen
fraction exceeds this value.
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
allowing detection of oxygen disconnection.
Note that, for Oxygen display, this is a measurement only, not a control setting. The
operator changes the measured oxygen fraction by altering the myAIRVO 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,
then press the Mode button to progress to the next
setting.
Press the Mode button to move to the next screen.
