Fi02 Monitor Calibration When the Fi02 Mon Calibration button is touched, the calibration menu appears. You have a choice of doing an ambient air calibration or a 100% oxygen calibration. Either can be done on or off a patient; however, be certain that the patient can tolerate room air or 100% oxygen for the calibration procedure, which takes approximately 4 minutes to complete. To exit the Fi02 Calibration screen, touch the EXIT button. 13 Vela User s Guide L1536 Rev. C Fi02 Monitor Calibration

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 increments of one minute. Pressing the nebulizer button again ends nebulization. Caution: Nebulizer output is not volume compensated during volume control breaths. Delivered volumes and peak inspiratory pressures will increase during nebulization. To ensure consistent tidal volume delivery, tidal volume should be reduced for the duration of the treatment. Nebulizer output is approximately 50 ml per half second of inspiratory time. Tidal volume is unaffected during pressure control breaths. Fi02 will increase slightly during nebulization. Delivered Fi02 during nebulization can be estimated using the following calculation; 2 2 ALARM SILENCE FREEZE MANUAL BREATH ALARM RESET INSP HOLD EXP HOLD New Fi02 = [(Vt x Fi02) + (0.1 x Ti)] [Vt + (0.1 x Ti)] NEBULIZER 100% O2 29 Vela User s Guide L1536 Rev.
