A philips field service engineer has been on site and has evaluated the device, as well as alarm logs.This investigation shows that the device worked as expected, and the issue could not be reproduced.Photographs of the alarm history have been provided for the reported timeframe which clearly show multiple alarms for this patient (extreme brady 58 bpm or heart rate low).The logs also show that the device provided several blue technical alarms (inops) to alert the staff that the ecg leads, and spo2 sensor were off at 10:30 am.The alarms were also turned off several times and then back on again (10:46 ¿ 10:47), and there was an asystole at 11:04 am.When a spo2 sensor has fallen off a patient, the device cannot measure the parameter, and therefore cannot provide alarms for a desaturation event, but would provide an inop ¿spo2 sensor off¿, as in this case.The issue has been resolved by instructing the user about alarms behaviour.This is all that was necessary to fully resolve the issue.The device remains at the customer site.This investigation determined there was no device malfunction.
