SETUP MENU SETUP MENU
This menu allows the user to set preferences and perform test and calibration procedures relative to patient
use. To access this menu, turn the ON/OFF switch to ON and press the SETUP key in the lower right
corner of the display. The SETUP key is only available immediately after powering on the unit and is
disabled as soon as any other key except ALARM QUIET or BATTERY is pressed or if no key is pressed
within 30 seconds of power-up. The SETUP menu will be displayed and the alarm LED will light. From
this menu, the CALIBRATION menu can be accessed by pressing the CAL MENU key or you can exit back
to the MAIN menu by pressing the MAIN MENU key.

This function is used to calibrate the Oxygen sensor cell. Due to the fact that O
output over time once exposed to atmosphere, a calibration should be performed once a month in order to
assure optimal accuracy.
discarded and a new sensor installed and calibrated.
To calibrate:
1. With the O Sensor cable plugged into the side of the CROSSVENT and the sensor out of the
2
breathing circuit and open to atmosphere, press the OXYGEN key.
2. If the sensor has been exposed to a higher level of oxygen than just air in the last 5 minutes or so,
then wait 3-4 minutes for the sensor to acclimate and then press the 21% key. Otherwise, you may
press the key immediately. When the 21% is calibrated, it will return to the OXYGEN menu and
the 21% will be green. If it is red, the calibration failed. Either replace the sensor and/or confirm
no elevated level of oxygen is present.
3. Place the oxygen sensor tee onto the patient connector on the Crossvent and connect a breathing
circuit with a test lung to the tee.
4. With the O sensor cable still plugged into the ventilator, install the O

5. Apply 100% oxygen to the ventilator input and set 20 cmH
6. Wait 3-4 minutes and then push the 100% key. When the 100% is calibrated, it will return to the
OXYGEN menu and the 100% key will be green. If it is red, the calibration failed. Either replace
the sensor and/or confirm the oxygen supply concentration is stable.
NOTE: It is important to use the correct reference gases (100 and 21%) when performing this calibration. A
worn out sensor will not calibrate accurately.

This test may be used to confirm the integrity of the patient circuit and its connections. To perform,
proceed as follows:
1. Set the Max Pressure to its maximum setting.
2. Connect the patient circuit with a test lung to the Crossvent.
3. Set the flow control to 10 LPM.
4. Press enter. The Crossvent will pressurize the system and indicate "TESTING", followed by either
"PASSED" or "FAILED" depending on the results. If it fails the test, check the patient circuit and
all connections for leaks and retest.

Allows the user to choose between setting Inspiratory Time or Tidal Volume in the menus. Press INSP
TIME and then exit the SETUP 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 press TIDAL VOLUME in the SETUP menu and
exit. Whichever is chosen will remain in effect until it is changed in this menu.
