Daily NO, NO2 and O2 Sensor Low Range Calibration

  1. A low range calibration must be performed each day when Inovent® is in operation

  2. NO therapy can be administered during the sensor calibration process but inspired gases are not monitored and gas monitoring alarms are disabled. The ventilator settings must not be changed during sensor calibration or an alarm condition may occur

  3. The calibration process can be stopped at anytime by pushing the control wheel to cancel an operation to exit to a normal display

  4. Calibration may take up to 5 minutes

  5. From a normal display with Inovent® delivery system operating, push the calibration button to reach the first calibration menu. The low range (room air) “NO NO2 and O2” option will be highlighted

  6. Push control wheel to start the low range calibration. All three sensors calibrate automatically at the same time. The calibration may take a few minutes

  7. When the calibration is successful, the display will read “calibration complete”. The main display area will read “Calibration of NO NO2 and O2 low range succeeded”

  8. Turn control Wheel to “Exit to Normal Display” and push to confirm
