The reported complaint of "system error, out of service, revert to manual cpr" on the autopulse platform (serial #: (b)(4)) was confirmed during functional testing and during archive data review.The investigation findings revealed that the root cause of the reported system error was due to a defective processor board.During visual inspection, no physical damage observed.The autopulse platform is a reusable device and was manufactured in (b)(6) 2008.The device has been operating over 10 years and has exceeded its expected serviceable life of 5 years.The archive data review indicated system error (latch error 203 - mailbox full) was observed, thus confirming the reported complaint.The initial functional testing could not be performed due to unclearable error message "system error, out of service, revert to manual cpr".Thus, confirming the reported complaint.To remedy the issue, the processor board was replaced.The ap platform was retested and passed all functional tests.The autopulse platform is ready for clinical use.Historical complaints were reviewed for service information related to the reported complaint and there was no similar complaint reported for autopulse with serial number (b)(4).The death was not related to the autopulse device.The autopulse is used as an adjunct to manual cpr in cases of clinical death.The benefit of using the autopulse is that it in part substitutes mechanical compressions for the physical labor of manual chest compressions.If the autopulse did not start or unexpectedly stops compressions, rescuer should revert to manual cpr, which is the standard of care.The autopulse was intended to be used as an adjunct to manual cpr on adult patients.In case of stoppage of autopulse the user reverts to manual cpr.The transition from autopulse to manual cpr by trained users is similar to the time necessary for rescuer rotation, and presents the same workflow as manual cpr.Hence, based on available information, the patients' outcome was not negatively impacted by the interruptions when compared to standard of care manual cpr.Death is an expected outcome for cardiac arrest.
