7.5 Performance
Verification
Performance verification confirms that the ventilator is operating correctly, and
does not verify performance according to specifications (see Section 7.7 for
the system final test procedure, which verifies performance according to
specifications).
Required equipment:
•
0.25-in. test orifice (P/N 332353)
•
Pressure tubing
•
Smooth inner lumen tubing
•
Whisper Swivel (P/N 332113)
•
Performance Verification Form
NOTE:
Tubing lengths between circuit components can vary. However, the
maximum length of the entire circuit should not exceed 72 inches.
Follow these steps to perform the performance verification:
NOTE:
Ventilator settings are saved in case of power loss. The ventilator software
revision determines how operation resumes following a power loss:
•
Software versions 11.0 - 11.11, 12.0 - 12.7, and 13.0 - 13.7: If AC
power is lost for approximately 10 seconds or less and the power
switch remains ON, the ventilator performs a system self test and
returns to normal operation using the same settings that were in
effect before the AC power loss.
If the AC power loss is longer than approximately 10 seconds and the
power switch remains ON, the ventilator performs a system self test,
displays the Exhalation Port Test screen, and does not resume
ventilation.
•
Software versions 11.12, 12.8, 13.8 and higher: If AC power is lost
for any length of time and the power switch remains ON, the
ventilator resumes operation that was in effect at the time of the AC
power loss.
•
For all software versions, if the power switch is turned OFF after AC
power is lost, when AC power is restored and the power switch is
turned ON: the ventilator performs the system self test, displays the
Exhalation Port Test screen, and does not automatically resume
ventilation.
1. Connect to the ventilator outlet in this order: smooth inner lumen
tubing, Whisper Swivel, test orifice, and pressure tubing.
2.
Vent Inop test:
Power on the ventilator. When the Test exhalation port/language screen
appears, remove the AC power cord from the back of the ventilator,
and confirm that the
Vent Inop
indicator (wrench) lights and the
audible alarm sounds.
