Touch-Turn-Touch� / Touch-Turn-Accept�

Changes to controls and displays are accomplished with a three-step technique.

1. Touch the control or display to be changed. 2. Turn the data dial to reach the desired setting.

3. Touch the control again OR press "ACCEPT" toconfirm the change.

Changes not accepted by either method within 15 seconds revertto previous settings. Press "CANCEL" prior to accepting proposedchanges to return to previous settings.

Fi02 Monitor Calibration Allows calibration of internal oxygen sensor.

(Comprehensive & Standard models only).

Vent Set-up: Allows setting of these functions:

Low Min Vol OFF Enable or disable an "OFF" setting

Panel Lock Enable or disable the front panel lock switch.

Fi02 Monitor Turns the Fi02 monitor on or off. (Comprehensive & Standard models only).

Altitude units of measure Toggles between feet and meters for the altitude setting.

Altitude setting Allows setting of altitude for accurate volume measurement.

Language buttons Select the desired language for the front panel.

Video Normal/Inverse Reverses the color configuration of the graphic interface.

For a complete explanation of each function, refer to the Vela Service Manual (P/N L1534).

* Denotes function for use by trained Service technician.


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.

Fi02 Monitor Calibration


New Patient Set-Up

1. Power on the ventilator and perform operational verification testing asdescribed in Chapter 2 of your Operator's Manual.

2. Select "NEW PATIENT". Touch "PATIENT ACCEPT"

3. Select Active or Passive Humidification.

4. Enter patient ID if desired.

5. Select �LEAK COMP� ON/OFF. Note: Default for NPPV A/C, NPPV SIMV; NPPV CPAP PSV; �LEAK COMPON�

6. Touch "SETUP ACCEPT"

The Set-up screen can be accessed at any time by pressing the "Setup" button on the bottom right corner of the touch screen.

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)]
