Manufacturer Narrative

The customer's complaint of the autopulse platform (b)(6) displayed user advisory (ua) 45 (not at "home" position after power-on/restart) message was confirmed during the archive data review.The customer was able to clear the user advisory (ua) 45 (not at "home" position after power-on/restart) with the help and guidance received from zoll technical support.User advisory is a clearable message designed into the platform to alert the operator that autopulse has detected one of several conditions.Per the autopulse resuscitation system model 100 user guide, if the driveshaft is not at its home position when the autopulse is powered on, a user advisory (45) will occur.This user advisory will persist until the driveshaft is returned to its home position.To clear a user advisory (45) pull up on the lifeband until the chest bands are fully extended (thereby moving the driveshaft back to its home position), and then restart.The customer's complaint that the autopulse platform (b)(6) displayed fault 16 (timeout moving to take-up position) after clearing ua45 was confirmed during the functional testing and the archive data review.The root cause of the reported fault 16 was a malfunctioning drive train motor, likely attributed to a failed component.Upon visual inspection, unrelated to the reported complaint, a crack on the front-end area of the front enclosure, multiple cracks on the screw well area of the bottom enclosure, and a crack at the left channel roller area of the top cover were noted.The observed physical damages appear to be the characteristics of user mishandling, such as a drop.The damaged parts were replaced to address the physical damages.The archive data review indicated multiple ua45 and fault 16 around the reported event date, confirming the reported complaint.During the functional testing, the autopulse platform failed to execute the take-up due to fault 16.The autopulse failed to achieve the target depth for take-up within the specified time of around 5 seconds due to a malfunctioning drive train motor (slipped bushing).Whenever the bushing slips, the drive train motor seizes and becomes unable to rotate.Upon inspection, it was verified that the brake gap was within the specification.After investigating, it was determined that the root cause of the device failing to achieve take-up and not performing compression, resulting in the displayed fault 16, was related to the malfunctioning drive train motor.The drive train motor was replaced to address the reported fault 16.Upon further testing, the autopulse platform failed the load cell characterization test unrelated to the reported complaint.The test result indicated that both the single-point load cells were over-reporting.The load cells were replaced to address the observed problem.Following service, the autopulse platform passed the run-in and final tests without fault or error.Historical complaints were reviewed for service information related to the reported complaint, and no similar complaints were reported for the autopulse platform with (b)(6).
