During preventative maintenance (pm), the autopulse platform sn (b)(6) failed the load cell characterization test.The root cause of the failure was a failed load cell, likely attributed to the age of the platform, failed component, or mishandling such as a drop.The autopulse platform was manufactured in 2018 and is over five years old.Upon visual inspection, missing head restraints on the top cover were noted.Missing head restraints do not render the autopulse platform non-functional.The patient head restraint wire could have been cut to free the patient from the platform, or the user could have been lifting the platform by holding the head restraints.The top cover needs to be replaced to address the customer's complaint.The autopulse platform passed the initial functional testing without error or fault.However, the platform failed the load cell characterization check due to a failed load cell and needs to be replaced.Zoll is awaiting customer approval for service repair.Historical complaints were reviewed for service information related to the reported complaint, and no similar complaint was reported for the autopulse platform with sn (b)(6).
