The reported complaint of the autopulse platform (serial #(b)(4)) does not power on with several autopulse li-ion batteries was confirmed during functional testing and archive data review.The root cause of the reported complaint was due to a blown capacitor on the motor controller, likely as a result of normal wear and tear.The autopulse platform is a reusable device and was manufactured in march 2013, and is more than 8 years old, past its expected service life of 5 years.During visual inspection, a cracked front enclosure, a broken battery compartment and a bent battery lock were observed.The observed damages are unrelated to the reported complaint.The probable root cause of these physical damages are likely due to user mishandling, such as a drop.The front enclosure, battery compartment and battery lock were replaced to address these physical damages.During archive data review, record shows the autopulse platform last power up on 7/21/2021, thus confirming the reported complaint.In addition, ua02 (compression tracking error) and ua45 (not at "home" position after power-on/restart) advisory messages on the customer's reported event date, unrelated to the reported complaint.User advisory is normally a clearable error message and is designed into the platform to alert the operator that autopulse has detected one of several conditions.Per the battery hangtag - advisory codes description and action, user advisory 2 is an indication that the autopulse® has detected a change in lifeband tension.This advisory can happen when the patient or lifeband is out of position, or if the lifeband is opened during active operation.The recommended actions to take for this type of user advisory are: ensure that the lifeband is properly closed.Pull up completely on the lifeband, ensure that both the patient and the band are properly aligned, and press restart.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.During the initial functional testing, the autopulse platform failed to power up; thus, confirming the reported complaint.Investigation revealed a blown capacitor on the motor controller, likely as a result of normal wear and tear.To remedy the power issue, the motor controller was replaced.Unrelated to the reported complaint, it was noted that the power distribution board (pdb) was replaced due to a burnt mark, likely as a result of normal wear and tear.Following service, the autopulse was subjected to the run-in test using the 95% patient large resuscitation test fixture (lrtf) with good known test batteries until discharged without any fault or error.The autopulse platform passed all the functional tests.Historical complaints were reviewed for service information related to the reported complaint, and there was no similar complaint reported for autopulse platform with serial number (b)(4).
