16. Set PEEP = 0.
17. With test lung and pneumotach removed, occlude patient circuit.
18. Observe several breaths, then pick the displayed Peak Press that best represents the average (this number may vary).
19. Divide the set TV (20) by the Peak Press (Example: 20 ml/46 cmH2O = 0.43 ml/cmH2O). This number is the compliance
factor.
Perform the following to verify volumes reported by pneumotach:
20. Install BMD pneumotach #4409 and BMD test lung #1021.
21. Keep settings the same as above except set PEEP = 5.
22. Observe several breaths, and then pick the displayed Peak Press that best represents the average.
23. Subtract PEEP from the Peak Press, and multiply by the compliance factor. This value equals the volume lost in the circuit
(Example: (32 cmH2O – 5 cmH2O) x 0.43 ml/cmH2O = 11.61 ml).
24. Add the volume lost to the displayed volume on the Alarm 1 screen (observe several breaths and use the representative
average volume). This volume should be within 20% of the set TV of 20 (16 – 24 ml) (Example: 11.61 ml + 9.50 ml =
21.11 ml).
4- TV/INSP PREFERENCE
Allows the user to choose between setting Inspiratory Time or Tidal Volume in the Main Menu when not using Constant
Flow. To select inspiratory time as the preferred setting, press INSP TIME and then the SETUP MENU key. Next is
displayed a screen asking whether or not to display Tidal Volume in the MAIN Menu. This is the set tidal volume, not the
corrected tidal volume. Respond YES or NO according to preference and press the SETUP MENU key. When the user
returns to the MAIN Menu, INSP (inspiratory) will be displayed below the RATE key in the MAIN menu, thereby allowing
the user to set an inspiratory time directly. If the user would prefer to set a Tidal Volume directly rather than an inspiratory
time, then pressing TIDAL VOLUME in the SETUP menu will accomplish this. Whichever is chosen will remain in effect
until it is changed in this menu.
5- LANGUAGES
Allows for the menus to be displayed in a different language.
6- VER (Version)
Indicates the software version installed.
7- SN (Serial Number)
