The customer reported that the companion 2 driver made a "fan sound"over a 24 hour period while supporting a patient.The customer also reported that the noise became progressively louder.The customer also reported that she changed both filters, but the noise did not change.The customer also reported that the patient was subsequently switched to the backup companion 2 driver.There was no reported adverse patient impact.This alleged failure mode poses a low risk to the patient because although the companion 2 driver exhibited a fan sound, the companion 2 driver continued to perform its life-sustaining functions.The companion 2 driver will be returned to syncardia for evaluation.The results of the investigation will be provided in a follow-up mdr.
