4.2 Pre-use Checklist
4.2.1 Daily Checklist
4.2.1.1 Hose and Cable Connections
Check for correct connections:
1. Ventilator drive gas inlet (1).
2. Oxygen (2) and Air (3) pipeline supply.
3. Bellows drive gas port on the control unit (4) and the
bellows assembly.
4. Exhaled gas port (5). The discharged gas may contaminate
the environment. Connect to an AGSS system if available.
5. Pressure monitor port and breathing circuit (6).
Check that the port on the rear of the control unit is
correctly connected to the port on the rear of the absorber
assembly.
6. Spirometer cable (7) (see section 4.1.7).
4.2.1.2 Ventilator Internal Test
Turn on the gas delivery switch (8), a short self-test is initiated:
1. The bellows is filled.
2. The ‘power -up’ screen is displayed.
3. The audible alarm sounds (two tones).
4. The ventilator displays the start-up selection screen.
NOTE: While machine power is ON, the Ventilator can be turned
OFF and ON, using the ventilator On/Off switch (9).
4.2.1.3 Function Test
1. Select Adult default settings using the touchscreen:
V
T
: 600 ml / BPM: 10 / I:E Ratio 1:2.0
Airway pressure limit: 38 cmH2O (fresh gas compensation
on).
2. Connect a 2-litre breathing bag to the patient connection as
a test lung.
3. Set a basal flow only (anaesthetic machine).
4. Select VOLUME CYCLE mode.
5. After 10 breaths check that the bellows returns to the top of
the housing.
Failure to return to the top of the housing indicates a leak
in the breathing circuit. Rectify the leak before clinical use.
6. Check the delivered tidal volume as indicated on the scale
printed on the bellows housing.
The value should be between 600 ml and 800 ml.
If the delivered tidal volume is outside this range, refer the
ventilator to a trained engineer.
7. Check that spirometer readings, once settled, show correct
delivery of 600 ±20 ml.
