1.
Attach a sensor between the test lung and the HMEF to measure flow and pressure.
2.
Apply suction for a minimum of 20 seconds.
3.
Turn gas flow is turned up to a minimum of 30 l/min on the controller (Gas Flowrate Knob).
4.
Open expiratory valve and gas are pushed against the PEEP valve.
5.
Open suction valve and the vacuum sucks out the pre-requisite amount of gas from the system.
6.
Monitor that PEEP pressure is maintained at all times.
DANGER
Do not conduct the Closed Suctioning Test while
the GeVentor is connected to a patient.
Pressure Relief Test:
The purpose of the Pressure Relief Test is to confirm that the maximum pressure reached in the GeVentor system does not exceed
80 cmH
2
O. The test allows for confirmation that the relevant alarms are activated when maximum pressure is reached.
To conduct the Pressure Relief Test, follow the steps outlined below:
1.
Disconnect the GeVentor from the patient.
2.
Attach a test lung to the patient circuit.
3.
Attach a sensor between the test lung and the HMEF to measure flow and pressure.
4.
Set ventilator to 275 ml tidal volume by operating the system under Volume Controlled Ventilation mode
5.
Enter volume of 275 ml with 10 cmH
2
O PEEP and 10 breaths/min
6.
Set maximum pressure of 35 cmH
2
O (Pmax on HMI setting)
7.
Compress the test lung until pressure alarms and ventilator stops inflating and alarms
8.
Record maximum pressure reached
9.
Set pressure to a maximum value achieved or 50 cmH
2
O (whichever is lower)
10.
Detach test lung and occlude patient end of the breathing system
11.
Record system pressure
DANGER
Do not conduct the Pressure Relief Test while the
GeVentor is connected to a patient.

Calibration
The GeVentor is calibrated at the factory prior to shipment to the customer. A calibration and inspection check of the device is
required every six (6) months by an approved and qualified service technician. Please contact the manufacturer should more
information and services be required with respect to the calibration of the GeVentor.
NOTE
Calibration checks and inspections must be
conducted irrespective of normal maintenance
tasks and cleaning requirements of the GeVentor.
