Determination of
Compressed-Gas Supply
and Usage Period
Example:
Compressed-gas supply
O2 cylinder: 3 L
Cylinder pressure (at cylinder pres-
sure gauge):
200 bar
Available compressed-gas supply,
200 x 3 = approx. 600 L
Usage period

(10 + 1) L/min
Switching to )jAir Mixes reduces the gas
consumption by 50%, i. e. the usage
period is increased to roughly 100 min.
Testing safety valve
With the same device settings and with
the patient connection sealed at the
non-rebreathing valve the max. airway
pressure should be between 50 and 80
mbar.
Testing compressed-gas supply and
minute volume
Insert catheter adapter, size 5 (M 25569)
into patient connection of non-rebreath-
ing valve.
Read off the max. inspiration pressure
at the airway pressure gauge for the MV
settings: 7, 15,20.
MV 7 L/min
Airway pressure 4 to 8 mbar
MV 15 L/min
Airway pressure 15 to 24 mbar
MV 20 L/min
Airway pressure 28 to 38 mbar
The Oxylog should switch at regular
intervals from inspiration to expiration.

The ventilation ratio of the Cxylog
should be between 13 and 17 min’.
Operational Use
The airway pressure gauge must be
observed all the time so that incorrect
ventilation can be detected in due time,
thus precluding risks for the patient!
Set ventilation ratio and minute volume
(MV) to suit patient concerned.
For rapid presetting:
The ventilation ratio and minute volume
(MV) scales each have three colour
bands for the specific patient groups
infants, children and adults.
