(b)(4).The opt980 optiflow + mask interface adapter is an interface used to deliver humidified oxygen 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 support the weight of the circuit and prevent the cannula being dislodged.Method: the complaint opt980e optiflow + mask interface adapter was returned to fisher & paykel healthcare (f&p) new zealand for investigation, where it was visually inspected.Results: visual inspection of the returned cannula revealed that the tubing was detached from the swivel connector.It was further observed that the tubing was stretched at the manifold and connector end.Conclusion: we are unable to determine the cause of the reported damage to the subject opt980e optiflow + mask interface adapter.However, the damage observed was likely caused by the tubing being pulled.All optiflow interfaces are inspected during production for visual defects including cracks, tears, inclusions, discoloration and stretching or deformation.Any product that fails the visual inspection is rejected.The subject cannula would have met the specification at the time of production.The user instructions which accompany the opt980e optiflow + mask interface adapter show in pictorial format the correct placement and fitting of the cannula and also warn: "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." "failure to use the set-up described above can compromise performance and affect patient safety.".
