The complaint rt041 full face mask is not available for investigation as it was not received by fisher & paykel healthcare (b)(4).Our analysis is accordingly based on information provided by the hospital and our knowledge of the product.The mask was reported to be in use for approximately 2-3 hours.The nurse also reported that during therapy, the patient was not restless and did not try to remove the mask.Without the complaint device, we are unable to determine that may have caused the problem reported by the hospital.If the complaint device was returned, it would have been visually inspected.The rt041 full face mask features a mask base, seal, and headgear.The mask seal is inserted into the mask base and is secured with glue.Each assembled mask seal is inspected to ensure it is correctly inserted and there are no unacceptable gaps between the seal and the base.Samples are taken and the mask seals are pulled apart after 24 hours to ensure they meet or exceed the required detachment force before the assembled product can be released.
