Preparation
Connecting gas supply
Supply from an O
cylinder
2
Only use compressed gas cylinders which comply
with national regulations and have been approved.
Use a full cylinder (cylinder pressure 200 bar).
Screw pressure reducer (2.7 to 6.0 bar delivery
pressure, 5 bar nominal pressure) to O
Only use a pressure reducer with a vent valve at
the outlet to limit the delivery pressure to approx.
10 bar in case of a fault!
Connect Oxylog 2000 to pressure reducer with
medical gas hose.
Turn cylinder valve slowly and open fully.
Do not fit any flow control valves or flowmeters in the
gas supply to Oxylog 2000!
The ventilator may not function properly.
Determining the pneumatic operation time
Example:
Cylinder pressure measured on the pressure gauge of
the pressure reducer: 200 bar
Liquid capacity of the O
cylinder: 2.5 L
2
Supply of medical gas: 2.5 L x 200 bar = approx. 500 L
Approximate operation time for Oxylog 2000
Example:
IPPV mode, frequency 10 1/min, V
Minute volume = 10 1/min x 1 L = 10 L/min
Medical gas supply [L]
Operation time =
(MV +1*) [L/min]
500
Operation time =
= approx. 45 minutes
11
The gas consumption is reduced by approx. 50 % and
the operation time increases to approx. 90 minutes when
Oxylog 2000 is switched to »Air Mix«.
