This report is based on information provided by philips remote service personnel and has been investigated by the philips complaint handling team.Philips received a complaint on the intellivue x3 indicating that "high values are displayed, patient is already slightly bluish and then abruptly goes down to 68." it is not known that the device was in use at the time of the event.A philips remote service engineer (rse) spoke with the customer and the customer alleged that spo2 values are sometimes delayed and sometimes did not correspond to the status of the patient.The rse informed the customer that in order to find the cause of the problems with the spo2 alarm, philips would like to check some points like compatibility of the sensor and extension cable, configuration of the alarm delay and the aeration, and quality of the spo2 discharge when the problem occurred.The rse also advised the customer to check whether the perfusion value was over 1.0 and the signal quality display was at least in the middle range.The rse did not receive any response from customer's end so no work was performed by philips.Based on the information available and the testing conducted we were unable to replicate the reported problem.The reported problem was not confirmed.The engineer provided their analysis findings however we are unable to confirm the final disposition of the device because the customer did not respond to requests for additional information.The investigation concludes that no further action is required at this time.If additional information is received the complaint file will be reopened.
