The autopulse platform (sn (b)(6)) was used for resuscitating a patient.During the compressions, the crew needed to reset the lifeband by pulling up on it three times.After resetting the lifeband (lot #unknown) and upon resuming compressions, the lifeband broke, the drive shaft spun, and the autopulse platform displayed a user advisory (ua) 45 (not at "home" position after power-on/restart) message.Per the customer, the lifeband broke at the hinged belt guards of the lifeband cover plate.The crew reverted to manual cpr for the rest of the call.No consequences or impacts on the patient.After returning to the station, the crew couldn't rotate the drive shaft to its home position and felt that the drive shaft was stuck.Please see the following related mfr report: mfr 3010617000-2023-00798 for the autopulse platform.
