When a ventilation mode is selected, the only
parameters shown are those affecting the
actual mode. Below are all the mode-related
parameters presented.
1. Respiratory rate (RR) Rate of controlled
mandatory breaths or used for calculation of
target volume (b/min).
2. Tidal volume (VT) Volume per breath or
target volume (ml).
Minute volume (Vmin) Volume per minute or
target Minute volume (ml/min or l/min).
Presentation can be configured to either tidal
or minute volume.
3. PC above PEEP Inspiratory pressure level
for each breath (cmH
2
O) in Pressure Control.
4. PS above PEEP Inspiratory pressure
support level for triggered breaths (cmH
2
O)
in Pressure Support.
5. Inspiratory rise time (T inspiratory rise)
Time to full inspiratory flow or pressure at the
start of each breath, as a percentage of the
breath cycle time (%), or in seconds (s).
6. I:E ratio (I:E) (Inspiration time + Pause
time): Expiration time.
7. Inspiration time (T
i
) Time for active flow or
pressure delivery to the patient (s).
8. Pause time (T
pause
) Time for no flow or
pressure delivery (% or s).
9. Trigger sensitivity
a) Below zero: Trigger sensitivity is pressure
dependant. The pressure below PEEP which
the patient must create to initiate an
inspiration (cmH
2
O) is indicated.
b) Above zero: Trigger sensitivity is flow
dependent. As the dial is advanced to the
right (step wise from the green into the red
area) the trigger sensitivity increases i.e the
inhaled fraction of the bias flow leading to
triggering is reduced.
10. PEEP Positive End Expiratory Pressure
(cmH
2
O).
11. Inspiratory cycle-off Fraction of
maximum flow at which inspiration should
switch to expiration (%).
