5.4 Device check
Always perform a Device Check before each ventilator use or after changing the
patient circuit.
The fabian ventilator does not automatically compensate gas fraction
measurements for changes in barometric pressure during use. The oxygen sensor is
calibrated in the hospital prior to use and this calibration remains in effect. This
calibration process is part of the normal pre-use checks for the ventilator. The pre-
use calibration should not be skipped if the ventilator has been moved to a
location with significant change in altitude.
Attach high pressure Air and Oxygen
supply hoses to the inlets on the rear
panel of the ventilator.
Connect hoses with the
corresponding wall outlets.
Air and Oxygen supply hoses
are correctly connected
