For frequencies of 5 to 40 1/min:
The mechanical strokes and their time parameters are
determined by the frequency set for SIMV/CPAP:
Rotary knob »TI : TE« is disabled in SIMV mode.
1 Switch for ventilation modes set to »SIMV/CPAP«.
Set the ventilation pattern for the mechanical ventilation
strokes
2 using the »VT«
and »Freq.« knobs.
A frequency of less than 10 1/min should preferably be
set to allow the patient sufficient time for spontaneous
breathing.
3 Display:
if the set frequency is lower than 18.5 1/min
or:
if the set frequency is higher than 18.5 1/min.
To clear the display:
4 Press »g Reset«.
The following message appears if the expiratory minute
volume is less than 1 L/min:
