Manual ventilation
with breathing bag
»PEEP« and pressure limitation »Pmax« are inactive.
The airway pressure is limited via the pressure limiting
valve APL.
1 Set pressure limiting valve APL to »MAN« and set
required ventilation pressure: turn valve head.
To fill system:
2 Press »O2 +«.
3 Set fresh gas with O2, N2O or AIR delivery valve –
● start manual ventilation.
Manual ventilation following a power failure
with breathing bag
(Only relevant if the machine is not equipped with an
uninterruptible power supply).
In the event of a power failure, the airway pressure
pushes the ventilator piston into its limit position, thus
increasing the system volume by up to 1.4 litres!
To compensate this:
1 Set pressure limiting valve APL to »MAN« –
3 temporarily increase fresh gas flow
or
2 press »O2 +«.
3 Set fresh gas with O2, N2O or AIR delivery valve –
● start manual ventilation.
Emergency ventilation following a gas failure
AIR changeover
The ventilator drive and ejector generating a negative
pressure in the secretion aspirator are normally supplied
with gas from the compressed air supply (AIR). If AIR
fails, the system automatically switches over to O2.
N2O lock and O2 shortage alarm
If O2 fails, an O2 shortage is signalled and the supply of
N2O disabled. The measuring tube block automatically
switches to AIR, regardless of the lever setting.
The patient must immediately be ventilated
with the separate emergency ventilation bag
if both O2 and AIR fail.
