Fi02 Monitor Calibration
When the Fi02 Mon Calibration button is touched, the calibration menu appears. You have a choice of doing an ambi-ent air calibration or a 100% oxygen calibration. Either can be done on or off a patient; however, be certain that thepatient can tolerate room air or 100% oxygen for the calibration procedure, which takes approximately 4 minutes tocomplete.
To exit the Fi02 Calibration screen, touch the EXIT button.

Synchronized Nebulizer
A high pressure oxygen source gas connection is required to power the in-line nebulizer. Nebulizer flow delivery is synchronized with inspiration.Nebulization lasts for up to 60 minutes and is user adjustable in incrementsof one minute. Pressing the nebulizer button again ends nebulization.
Caution: Nebulizer output is not volume compensated during volume controlbreaths. Delivered volumes and peak inspiratory pressures will increase dur-ing nebulization. To ensure consistent tidal volume delivery, tidal volumeshould be reduced for the duration of the treatment. Nebulizer output isapproximately 50 ml per half second of inspiratory time. Tidal volume is unaf-fected during pressure control breaths.
Fi02 will increase slightly during nebulization. Delivered Fi02 during nebulization can be estimated using the following calculation;
New Fi02 = [(Vt x Fi02) + (0.1 x Ti)][Vt + (0.1 x Ti)]
