O Air Supply
• 2 L test lung (or two 1 L test lungs in parallel)
• Calibrated Spirometer
• Patient Circuit, Adult-without PEEP
• Stopwatch or breath rate meter
When doing a performance checkout, always:
• Allow the vent to warm up by operating at nominal settings for 1 hour, or warm up to ≥ 95° F
in Servo mode with 10 Lpm at 4000 rpm settings, before beginning the performance
checkout.
• After changing the control values for each test, allow ventilator to operate for 3 minutes.
NOTE
When the Extended Features PRESETS, PTNT QUERY menu option is set to QUERY ON and the
ventilator is powered up in normal ventilation mode, ventilation and alarm activation are suspended
and the message SAME PATIENT is displayed after completing POST tests.
Press the Select button to enable the suspended alarms and begin ventilation with the settings in

1) Perform a Tidal Volume test.
A) Set the ventilator as follows:
PEEP: 5 cmH
2
O
Tidal Volume: 1500 ml
Breath Rate: 6
Insp Time to 6.0 seconds
• Average measured volume (BTPD) must be
1500 ± 150 ml.
• Average monitored tidal volume (Vte on the
display) must be ±15% of average measured
volume.
B) Set the ventilator as follows:
Tidal Volume: 1500 ml
Breath Rate: 8
Insp Time: 3.0 seconds
• Average measured volume (BTPD) must be
1500 ± 150 ml.
• Average monitored tidal volume (Vte) must be
±15% of average measured volume.
C) Set the ventilator as follows:
Tidal Volume: 1500 ml
Breath Rate: 10
Insp Time: 1.5 seconds
• Average measured volume (BTPD) must be
1500 ± 150 ml.
• Average monitored tidal volume (Vte) must be
±15% of average measured volume.
