Ventilation
Manual/Spontaneous Ventilation Mode
ManSpont (Manual/Spontaneous) is a non-auto-
matic mode of ventilation. However, the ventilation
monitor and alarms are still operational. In
ManSpont mode, the ventilator piston is moved par-
tially upward to reduce system compliance. Manual
ventilation (with APL valve pressure limit) can be
delivered with the APL valve in the MAN position.
Spontaneous ventilation (APL valve wide-open)
can occur with the APL valve in the »Spont« posi-
tion.
The following examples and illustrations describe
starting Man/Spont ventilation from the present
ventilation mode »Volume Control«:
For Spontaneous Breathing:
z Rotate the APL valve knob fully counterclock-
wise until the index mark on the knob lines up
with the index mark on the bottom of the
valve.The valve is now open for spontaneous
patient breathing.
z Set the appropriate fresh gas flow.
1 Press the »ManSpont« key. The LED associ-
ated with this key starts blinking. It remains
blinking until the selected mode of operation is
confirmed.
2 The Waveform window is replaced by the
ManSpont window and a message that pro-
vides instructions to confirm the mode change.
