The autopulse platform in complaint was returned to zoll on (b)(4) 2014 for investigation.Investigation results as follows: visual inspection was performed and the following was observed: the head restraint wire was cut/broken and the front enclosure was cracked.Based on the condition of the returned platform, the observed damages were due to wear and tear.During power on of the platform, a user advisory (ua) 7 fault (discrepancy between load 1 and load 2 too large) was displayed on the platform.Inspection of the device determined a failed load cell was the cause for the ua 7.The ua 7 fault is considered unrelated to the reported complaint.The reported user advisory (b)(4) message (patient temperature sensor failure) was not observed during functional testing.The platform ran for 15 minutes with a large resuscitation test fixture and an additional 10 minutes with a test mannequin with no faults observed.A review of the archive did not show the reported ua (b)(4) occurring on the reported event date of (b)(6) 2014.The fault was however observed on other dates, including most recently on (b)(6) 2014.Based on the investigation, the part(s) identified for replacement were the top cover, front enclosure, single point load cell.The patient temperature sensor was also replaced as a precaution to prevent future ua (b)(4) errors.In summary, the reported complaint of a ua (b)(4) fault occurring was confirmed during archive review.The patient temperature sensor was replaced as a precaution to prevent future ua (b)(4) errors.During functional testing, a ua 7 fault was displayed and attributed to a failed load cell.The reported complaint of the head restraint being damaged was confirmed during visual inspection and attributed to wear and tear.Following replacement of the damaged parts as well as the load cell and patient temperature sensor, the device passed all testing criteria.
