5.22 Fresh Gas Calibration (2)
The ventilator must be in STANDBY. The fi rst reading is at ZERO. Therefore,
because of the basal fl ow set on the fl ow meters, the only option is to disconnect
all oxygen supplies (cylinders and pipeline). All other gases must be reduced to
ZERO fl ow on the fl ow tubes. A warning message will be displayed stating LOW
SUPPLY GAS. Ignore this message for this test. The fl ow tubes themselves are
accurate enough for this calibration but an external fl ow monitor can be used to
check if required.
From this menu, select Fresh Gas.
1. Set Zero fl ow (on the fl ow tubes), then Confi rm.
2. Set 1 L/min (on the fl ow tubes), then Confi rm.
3. Set 2 L/min, 3 L/min, 4 L/min, 5 L/min, 6 L/min, 7 L/min, 8 L/min, 9 L/min,
10 L/min and, fi nally, 20 L/min
If all is correct, the ventilator will bleep and state DONE on the screen. After a
few seconds, you will be returned to the normal run screen.
If an error occurs, the calibration will be aborted. The only reason for this error
is that there was not a step change between one calibration point and the next.
5.23 Absorber fi tted (3)
This option allows the ventilator to be used with a system that does not have a
BAG/VENT detect switch fi tted.
5.24 Sigh (4)
This option allows the fi xed sigh amount to be set. For example, every 10
breaths a 10% extra will be delivering. Select one of the parameters in the base
to change using the arrow keys or use the Trakwheel™.
