Manufacturer Narrative
|
The companion 2 driver was returned to syncardia for evaluation.Review of the patient file revealed multiple external air connected notifications.This is an indication that the necessary conditions required for the driver to operate exclusively on external air were not consistently met, thereby causing the driver to disable the external air connected icon and activate the primary compressor.This confirmed the customer-reported issue.Investigation testing was performed to reproduce the "compressor cycling" as observed by the customer.During the observation run, intermittent compressor cycling did occur, thus reproducing the customer experience.A malfunction of the manual pressure regulator to maintain the required pressure set point value was identified as the root cause.The issue of compressor cycling because of a malfunction of the manual pressure regulator is being investigated in a capa (corrective and preventive action).The capa will document the investigation including, but not limited to, potential root cause and corrective actions associated with compressor cycling because of a malfunction of the manual pressure regulator.Syncardia has completed its evaluation of this complaint and is closing this file.(b)(4).
