(b)(4).The opt844 interface is used to deliver humidified oxygen to patients.The opt844 consists of a lightweight delivery tube which is connected to a rigid plastic base and soft nasal prongs (nasal interface).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 nares.The complaint opt844 nasal cannula was not returned to fisher & paykel healthcare (fph) as it had been destroyed by the hospital.The airvo humidifier used during the incident was tested by the hospital medical physics department and found to be functioning correctly, with no fault.Following notification of this incident an fph representative visited the hospital and spoke to the attending staff in order to obtain further details about the incident.We were informed that the cannula had been in use on the patient for about 10 hours prior to the incident.Staff were unable to comment on what may have caused the reported incident.They had disposed of the complaint cannula and had not noted whether it was damaged in any way.The cannula had been in use for 10 hours prior to the event, which suggests that there was no damage to the device when it was put into use.Given that the airvo humidifier had reportedly sounded a blockage alarm it is possible that the prongs had become kinked, thus occluding flow.Without the cannula to evaluate we are unable to confirm what may have caused the reported incident.All optiflow interfaces are inspected during production for visual defects including cracks, tears, inclusions, discolouration and stretching or deformation.Any product that fails the visual inspection is disposed of.Our user manual that accompanies the airvo humidifier instructs the user to "use continuous oxygen monitoring on patients who would desaturate significantly in the event of disruption to their oxygen supply." the user manual also states that the "airvo is for the treatment of spontaneously breathing patients who would benefit from receiving high-flow, warmed and humidified respiratory gases." and that "the unit is not intended for life support.".
