INOmax® DSIR Troubleshooting Warning: Use caution when troubleshooting the INOmax DSIR while in use for a patient. When possible replace the unit in question, and perform troubleshooting procedure once the unit is removed from the patient. If the system fails to operate properly: 1. Check the patient condition and take appropriate action. 2. Verify that the system is set up as detailed in Section 2/ Setup of the Operation and Maintenance Manual. 3. Use the INOblender® (see INOblender Operation Manual) or backup mode if necessary (see page 29 of manual). 4. Find a symptom or alarm condition in the troubleshooting table which best describes the problem and follow the recommended actions to resolve the problem. If the problem can’t be corrected: Contact Customer Service on 1300 198 565. Troubleshooting Guide High Priority Alarms Symptom/Alarm 1. High NO Alarm High NO Possible Cause Recommended Action A.Note: A newly installed NO sensor will give high readings until fully conditioned (about 5 hours) and calibrated. a. After installation of the NO sensor perform a low and high calibration. B.The High NO alarm level may be inappropriately set. a. Make sure the High NO alarm is set greater than the Set NO value. C.The NO calibration may have drifted. a. Perform a low and high range calibration of the NO sensor. b. Wait 5 hours and repeat both the low and high calibration. b. Check calibration sample tee for leaks. D.Circuit setup incorrect. a. Check circuit setup for correct use of adapters and/or check valves. High Priority Alarms Symptom/Alarm 2.LowNOAlarm Low NO Possible Cause Recommended Action A.ThePatientGasSamplelinemaybe disconnected. a. ReconnectthePatientGasSampleline. B.TheLowNOalarmsettingmaybe inappropriatelyset. a. MakesuretheLowNOalarmissetlessthan theSetNOvalue. C.TheNOcalibrationmayhavedrifted. a. Performalowandhighrangecalibration oftheNOsensor.
