Min P (AVAPS
Minimum IPAP
Pressure) The minimum pressure to be applied.
NOTE: When you adjust the AVAPS minimum and maximum pressures, remember that
IPAP is adjusted to meet the target value. If the calculated target pressure is
outside of the minimum and maximum pressure range, the target volume will
not be achieve
d.
Applies in AVAPS mode only.

Oxygen concentration to be delivered. 21 to 100%
PPV % Percentage of PPV assist or gain. This gain
is applied to the Max E and Max R settings,
yielding the applied Elastance and Resis-
tance assist values.
Applies in PPV mode only.
0 to 100%
Ramp Time An interval during which time the ventilator
linearly increases pressure, helping to re-
duce patient anxi-
ety. OFF, 5 to 45
min
Rate (Respirato-
ry Rate) Respiratory frequency or number of breaths
per minute.
Inverse ratio ventilation is not allowed.
4 to 60 BPM
Rise (Rise Time) Speed with which inspiratory pressure rises
to the set (target) pressure.
If the Rise Time is insufficient to reach the
target IPAP pressure, adjust the Rise Time
or I-Time setting.

Setting Description Range
Max E and Max R are multiplied by PPV
% to obtain the applied Elastance assist
and Resistance assist values. Here a Max
R setting of 4 cmH
2
O/L/s and a PPV %
setting of 30% yield a Resistance assist
value of 1.2 cmH
