Power failure
(manual ventilation is still possible)
●
The master power switch must be pressed.
The audible power failure warning is muted after
45 seconds.
●
Deliver fresh gas and set the pressure limiting valve
(APL). If necessary press the O

Flush key (»

If there is a power failure, the ventilator piston is
forced back to its end position by the airway
pressure, thereby increasing the system volume
by max. 1.4 litre.
Gas failure
If AIR
(medical compressed air)
fails
– Cato automatically switches over to O

.
If O

fails
– Cato automatically switches over to AIR. An audible
warning is emitted (O

Ventilate the patient immediately with the
separate emergency ventilation bag!
Auto-WakeUp
Manual ventilation cannot be performed in standby mode.
Any attempt to perform manual ventilation in standby
mode is detected by the system on account of the
pressure thrust in the breathing bag and it automatically
switches to »
MAN/SPONT
« mode in which manual
ventilation can then be performed. The background
lighting of the flow measuring tubes goes on at the same
time.
The system is protected against excess static pressures:
The system pressure is relieved automatically if an excess
static pressure of more than 30 mbar is present for more
than 60 seconds.
Dräger recommends that manual ventilation should
always be started by pressing the »
MAN/SPONT
« key.
