This incident is being re-evaluated as part of newly implemented procedures.Due to the customer initially stating the patient experienced pneumothorax after using the ipv device, this incident is deemed reportable.The site completed their own internal investigation and through additional x-rays of the patient taken post ipv therapy, it was determined that the ipv device did not actually cause the patient pneumothorax.The site contact stated that after the ipv use, an x-ray was completed, confirming no pneumothorax was present.The pneumothorax presented itself some time later that day, again via x-ray, well after the device had been used initially.Percussionaire received the device back for internal investigation.The device passed all functional tests and was noted to be performing as intended.It has been determined that the device did not cause patient pneumothorax at this time.No additional information has been received on patient status.If any additional information is received for this incident, a follow up mdr will be filed.
