Configuring Ivaps - ResMed VPAP ST-A User Manual

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
• directly entering the target values.
Using Learn Targets
Learn Targets monitors the patient's resting ventilation, with the goal of learning the patient's Target
Alveolar Ventilation and Target Patient 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.
1. Select Learn
Targets from the
Settings screen in
iVAPS mode.
During the Learn Targets cycle, the device delivers two pressures: EPAP and Pressure Support without
backup breath (like S mode). Ensure the patient remains comfortable, breathing is stable and leak is
minimised, particularly in the final five minutes.
Entering the target values
The Target Va can also be determined to adopt a Target Patient Rate using a settable Target Va parameter
and patient height.
1. Select Target Va
from the Settings
screen in iVAPS
mode.
2. Press to start
the 20-minute
Learn Targets cycle.
2. Press and turn
to set the Target
Va as required.
The equivalent
MV, Vt and Vt/kg
are automatically
calculated and
displayed.
3. Tidal Volume and
Respiratory Rate
are recorded for
each breath. Target
Va and Target Pt
Rate are then
calculated from
these two recorded
paramaters.
3. Press to
confirm. The
selected Target Va
will then be applied
to iVAPS therapy
settings.
4. If the target values
are acceptable,
select Accept
and therapy will
commence in
iVAPS mode. If not
acceptable, select
Cancel and therapy
terminates.
