Configuring iVAPS
There are two ways in which you can configure iVAPS mode:
•
using Learn Targets—learns the patient's breathing pattern and calculates the target values
automatically, or
•
entering the target values manually.
Using Learn Targets
Learn Targets monitors the patient’s resting ventilation, with the goal of learning the patient’s Target
Alveolar Ventilation (Target Va) and Target Patient Rate (Target Pt Rate) in preparation for iVAPS
mode.
After the final circuit configuration (includes patient’s height, EPAP, appropriate mask or tube
settings and any supplemental oxygen added) is achieved, follow the procedure below. The device
must be in standby to start the Learn Targets cycle.
During Learn Targets, Tidal Volume and Respiratory Rate are recorded for each breath. Target Va
and Target Pt Rate are then calculated after 20 minutes. Ensure the patient remains comfortable,
breathing is stable and leak is minimised, particularly in the final five minutes.
Note
: iVAPS and AutoEPAP will only be initiated once Learn Target values are accepted.
To use Learn Targets:
1.
In
Settings
menu, select
iVAPS
mode and make any required parameter changes.
2.
Select
Learn Targets
. The Learn Targets cycle will begin.
3.
If the target values are acceptable, select
Accept
and therapy will commence in iVAPS mode. If
target values are not acceptable, select
Cancel
and therapy will terminate.
