Mandatory (PCV) settings (760 Ventilator only) (continued)
INSPIRATORY
PRESSURE
(760 only)
T I /I:E RATIO
(760 only)
RISE TIME
FACTOR
(760 only)
Pressure above PEEP during
the inspiratory phase of a PCV
breath.
You can use the MENU key to
select inspiratory time (T I ) or
I:E ratio as the breath timing
setting for a PCV breath. You
can change the selected
breath timing setting (T I or I:E
ratio), but the setting remains
constant when you change
the respiratory rate in PCV.
Selecting I:E ratio makes the
set ratio of inspiratory time to
expiratory time for a PCV
breath.
The time for inspiratory
pressure to rise from 0 to 95%
of the target pressure level
during a PCV breath.
A setting of 100 = a 100-ms
rise time, and a setting of
5 = 80% of the inspiratory
time or 2500 ms, whichever is
less.
When you adjust this setting,
the message window shows
the actual time (in seconds) to
reach 95% of target pressure.
5 to 80 cmH 2 O (5 to 80 hPa)
Accuracy:
± (3 + 2.5% of setting) cmH 2O
Inspiratory time (T I ):
0.2 to 8 seconds
Accuracy: ± 0.05 second
I:E ratio: ≤ 4:1
Accuracy: ± (0.1 + 2%)
5 to 100
NOTE:
To help determine the correct setting for inspiratory time, during
PCV the message window displays peak inspiratory flow, end
inspiratory flow, and end exhalation flow in L/min.
