The reported complaint that "the autopulse lifeband (lot # 170557) had been twisted was confirmed during the visual inspection of the returned lifeband.The probable root cause of the reported complaint was likely incorrectly installed lifeband or the patient displacement/ shift on the platform during the compressions.During the visual inspection, observed the belt on band 1 was twisted, thus confirming the customer's complaint.In general, a twisted belt should not affect the functionality of the lifeband.In addition, both of the protective band sleeves were cut/torn open by the customer, unrelated to the reported complaint.It is possible, the customer wanted to verify the twisted lifeband.Functional testing could not be performed due to the observed damages on the returned lifeband.Historical complaints were reviewed for information related to the reported complaint, and there was no previous history of complaints reported for lifeband with lot# 170557.
