Investigation results for the returned platform as follows: visual inspection of the returned platform shows that the top cover, encoder cover, and the battery compartment were damaged.In addition, the battery partition cover and the patient restraint pin were missing.The physical damages found during visual inspection confirmed the reported issue of the separated right hand side of the platform and the missing top side pin.The damages appear to have been caused by normal wear and tear (autopulse manufactured in august of 2005).Review of the archive was performed and the reported complaint of the platform stopping compressions was confirmed.The archive data shows that no sessions occurred on the reported event date of (b)(6) 2014.However, the archive shows that user advisory (ua) 2 (compression tracking error) and ua 18 (max take-up revolutions exceeded) occurred on (b)(6) 2014.Functional testing could not be performed due to defective load cells.The load cell count for each cell was hardly increasing with additional weight placed on the platform.Based on investigation, the parts identified for replacement are the top cover, encoder cover, battery compartment, battery partition cover, and the load cells.In summary, the reported complaint of the platform stopped compression was confirmed based on the archive review and during functional testing.The faults were found to be due to the defective load cells.The reported issue of the separated right hand side of the platform and the missing top side pin was confirmed during visual inspection.Upon replacement of the load cells and the damaged parts, the platform passed all testing criteria.
