(b)(4).The opt980 interface is used to deliver humidified respiratory gases to patients.The interface is held in place by a head strap and also includes a lanyard which is placed around the patient's neck or attached to the patient's clothing or bedding to remove the load of the breathing circuit from the patient's interface.Method: the two complaint opt980 mask interface adapters were returned to fisher & paykel healthcare in (b)(4), where they were visually inspected.Results: device 1: visual inspection of the opt980 device revealed that the tubing was torn and stretched.The lanyard accompanying the device was in its original packaging.Device 2: visual inspection of the opt980 device revealed that the tubing was torn and stretched.The tubing was returned without the mask adapter.Conclusion: we were unable to confirm the exact cause of the reported fault.However, it was mostly likely that the disconnection occurred as a result of pulling force being exerted on the device by the user or the weight of the breathing circuit pulling at the tube.All optiflow interfaces are inspected during production for visual defects.Any product that fails the visual inspection is rejected.Our user instructions that accompany the opt980 mask interface adapter has a pictorial diagram showing the correct use of the lanyard and tube clip.It also states: appropriate patient monitoring must be used at all times.Failure to monitor the patient may result in loss of therapy, serious injury or death do not crush or stretch tube, to prevent loss of therapy.
