The autopulse platform (b)(4) was returned to zoll for evaluation.The customer complaint was confirmed during visual inspection.It was also found (unrelated to the reported complaint) that the battery lock was bent.To resolve the issue, the top cover was replaced.The autopulse platform is a reusable device and was manufactured on (b)(6) 2013.Therefore, this type of issue is characteristic of normal wear and tear for the life of the device.Review of the archive data found multiple user advisory (ua) 12 (lifeband not present) error messages had occurred on (b)(6) 2016 and ua 41 (patient temperature sensor failure) on (b)(6) 2016.During further investigation, the user advisory 12 (lifeband not present) error message appeared upon powering on the device.As a result, functional testing could not be performed.To resolve the ua 12, the switch arm assembly was adjusted so to be parallel to the case.The platform was tested and ran for approximately 30 minutes with no faults found.Although the ua 41 could not be duplicated during investigation, the power distribution board and temperature sensor cabling were replaced to avoid the reoccurrence of ua41.Historical complaints were reviewed for service information related to the reported complaint and there was no previous history of complaint reported for autopulse with serial number (b)(4).The platform passed all critical testing.
