Operating the Ventilator
5-6 Operator's Manual
2.
Ensure the ventilator, patient circuit, and accessories are assembled correctly, as described in Chapter
3 .
3.
Make sure the ventilator has passed the quick check procedure.
4.
Perform the circuit check. Resolve any issues. Reference Circuit Check Button on page 4-5 .
5.
Set all parameters per physician’s prescription using manual adjustment or a custom or default preset.
Reference Chapter
9 for specifications on all settings.
a.
Select mode and breath type. Set all parameters on the Main screen and relevant parameters on
the More screen.
b.
Select safe/appropriate alarm limits on the Alarms screen.
c.
Ensure that the alarm loudness is set loud enough for the alarm to be heard under all circumstanc-
es.
6.
Place a test lung on the patient end of the breathing circuit, and press the Start Ventilation button on
the touch screen.
7.
Ensure that the ventilator starts operating appropriately.

Note:
Flow and volume are set and measured at the ambient temperature pressure saturated (ATPS) condition.

Note:
While ventilating a test lung, peak pressure for volume breaths and volume delivery for pressure breaths
will be different than they will be on the patient. Pressure Support breaths will not perform the same way
they do on patients. And PEEP may cause auto-triggering. These differences may cause nuisance alarms
during this step.
8.
When ready, remove the test lung and attach the patient connection of the breathing circuit to the
patient interface.
9.
Monitor the patient settings and check for appropriate alarm settings.
10.
Verify that the patient trigger icon lights each time the patient initiates a spontaneous breath. Re-
adjust sensitivity (Ptrig or Flow trig if using on-airway flow sensor) as necessary to ensure comfortable
triggering without auto-triggering. When using PEEP while ventilating a patient with an airway leak,
set NIV to on and adjust bias flow to stabilize the PEEP and eliminate auto-triggering at reasonable
trigger settings.
11.
Closely monitor the patient and ventilator to ensure appropriate oxygen delivery, and adequate oxy-
genation and ventilation.

WARNING:
Always ensure adequate monitoring is in place when ventilating patients.
