The affected device was returned and engineering was able to review the product through the packaging and determined that the mask port was deformed.The device was opened by engineering and was attempted to be attached to the valve patient port.Engineering determined that even though the mask port was out of round the mask was still able to be attached to the valve patient port without excessive force and created a good seal at the connection point.All masks processed through production are 100% inspected for this type of defect and would be scrapped if found during production.The defect is likely a result of transit/post processing.
