Philips received a complaint on the intellivue mp70 indicating that the monitor did not call the oxygen saturation (spo2) alarm for alarm limit set at 80 until patient was at 30.The remote service engineer (rse) spoke to the customer and had the customer simulate spo2 red and yellow alarms, and he got the visual and audio alarms.The rse planned to dispatch a field service engineer (fse) to go onsite to check the clinical audit trail for the alarm that customer claims was missed.The onsite service was canceled, because the fse troubleshot with the customer over the phone.Once the customer rebooted the monitor, it started working properly.The customer called the nurse over and tested the spo2, and the monitor was working normally.Based on the information available and the testing conducted, the cause of the reported problem is unknown, as the reboot resolved the issue, the cause was unable to be traced to one thing and is unknown.The reported problem was confirmed.The customer advised that the monitor is currently working normally.The investigation concludes that no further action is required at this time.
