Additional Manufacturer Narrative
A getinge technician was sent for investigation on 2026-03-16.During visual inspection the hls cable was found corroded on the hls side.The customer requested a replacement hls cable as well as a spare cable.The technician performed safety, calibration, and functionality checks to factory specifications.All function tests are passed.A follow-up medwatch will be submitted when additional information becomes available.
Event or Problem Description
The event occurred in usa during a training.It was reported that the pressures could not be zeroed.The customer stated that the hls cable is giving erratic pressure values across multiple circuits.The customer believes that the hls cable is twisted and bent and suspects it is damaged.No harm to any person has been reported.A pressure reading issue, can lead to a pump stop, if the intervention is set by the user, therefore a report is required.Complaint id: (b)(4).
