The pressure gauge must indicate a pressure over 30
cmH
2
O when the bellows completes its downward travel.
The pressure should not exceed 3 cmH
2
O at the end of the
expiratory phase when the bellows completes its upward
travel.
B. If the system is equipped with a PEEP valve, verify the
PEEP valve’s performance. Attach a breathing bag to the
patient Y-piece with an appropriate adapter such as an
NAD combination mask elbow with a 22 mm male fitting
for the breathing bag and 15 mm male fitting for the
Y-piece. With the manual/automatic selector valve in the
AUTO position, set the ventilator to the preferred
frequency.
Set the PEEP bypass switch to the PEEP ON position.
Then adjust the PEEP valve to different values and
observe the breathing system pressure gauge to verify
performance. Turn the PEEP valve control knob fully
counterclockwise to its lowest setting after the test is
completed. Set the PEEP bypass switch to the PEEP OFF
position.
Monitors
10. Check the alarm limit settings. The monitor alarm limits are
automatically set to a default configuration when the SYSTEM
POWER switch is turned on. Check these settings and adjust
them if necessary. Alarm limits can be adjusted at the beginning
of or during a procedure. Also, make sure that any external
monitors (if any) are connected properly and that the alarms
sound through the anesthesia machine’s central audio
annunciator.
*11. Test the alarm functions for all monitors. Simulate alarm
conditions and check for appropriate alarm signals.
System Flush
12. Flush the system with 100% oxygen by pressing the oxygen flush
button.
Fresh Gas Oxygen
Sensor Adapter
Option Verification
13. If the optional fresh gas oxygen sensor adapter is installed, make
sure the fresh gas hose connection is intact and not occluded.
Verify that the oxygen analyzer is properly calibrated. (See
Operation - Oxygen Monitoring “Calibrating the Oxygen Sensor”
in Section 5 for more information.) When removing the oxygen
sensor during calibration, insert the oxygen sensor port plug into
the fresh gas adapter port.
