(b)(4).Physio-control was made aware by the customer that they performed their own investigation of the reported event.After the event, the initial quik-combo defibrillation electrodes were placed on a staff member and connected to the first defibrillator used in the event.There was no connection made.The same defibrillation electrodes were connected to the second device used during the event and again no connection was made.Upon connecting and reconnecting the defibrillation electrodes numerous times, a slight ecg trace/noise on the display of the monitor was observed.It was noted that connection was observed only when the connector of the quik-combo defibrillation electrodes was squeezed tightly at the connection point between the defibrillation electrodes and the defibrillation therapy cable of the device(s).A new set of quik-combo defibrillation electrodes were placed on another staff member and immediately a connection was made with both defibrillators used during the event.The quik-combo defibrillation electrodes used during the event were discarded.The device(s) and the quik-combo defibrillation electrodes used during the event were not returned to physio for evaluation.The root cause of the reported issue could not be determined.Device not evaluated by manufacturer.

The customer contacted physio-control to report that during a patient event a set of their quik-combo defibrillation electrodes was unable to detect the patient.The customer checked their device, the defibrillation therapy cable, the connection between the defibrillation therapy cable and the quik-combo defibrillation, and the electrode pad adhesion to the patient but there was still no connection between the device and the patient.The customer advised that the device prompted them to ¿connect electrodes¿ when the defibrillation electrodes were connected to the patient.The same quik-combo defibrillation electrodes was used with a second device and again a connection was not made.A new set of quik-combo defibrillation electrodes was used with the second device and then a connection was made.The customer was able to successfully deliver 200 joules to the patient.There was approximately 2 minutes of delay.This issue is patient related; however there was no adverse patient outcome reported.Physio-control has attempted to contact the customer for further information on the event and patient, but has been unsuccessful.
