The autopulse platform was returned to zoll on (b)(4) 2014 for investigation.Investigation results as follows: visual inspection of the returned platform showed no physical damages to the platform.However, it was observed that an autopulse li-ion battery ((b)(4)) was stuck in the platform which confirmed the initial reported complaint.Visual inspection of the battery showed that the guiding pin on the right side was damaged.This damage confirmed the reported event that the battery was stuck in the platform.A review of the battery's archive was performed.The archive data did not show any issues.A review of the autopulse platform's archive was performed and showed that multiple user advisory (ua) 45 (not at "home" position after power-on/restart) faults occurred on the reported event date of (b)(4) 2014.However, the observed ua 45 faults are not related to the initial reported complaint that the battery was stuck in the platform.Battery management assessment was performed through review of the platform's archive.The archive data shows that ua 13 (battery fault detected) faults occurred with li-ion battery ((b)(4)) and with nimh battery ((b)(4)) on the reported event date.An investigation conducted using the batteries' serial numbers found that both of the batteries were within its expected life span of 2-4 years and that they were properly maintained.Functional testing was performed and the platform passed testing.The platform ran for 6 minutes with a test mannequin and no problems were observed.Based on the investigation, no parts were identified for replacement.In summary, the initial reported complaint that the battery was stuck in the platform was confirmed during visual inspection.The fault was found to be due to the damaged guiding pin.The root cause for ua 45 faults could not be determined.Per the autopulse® resuscitation system model 100 user guide ((b)(4)), 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.The battery management assessment results are unrelated to the initial reported complaint.The root cause for ua13 could not be determined.The platform was evaluated through functional testing and passed all testing criteria.
