It was reported that due to air bag leakage, the ventilator alarm went off and air could not be delivered normally, requiring replacement of the tracheostomy tube and accessories.There was patient involvement, but no harm/adverse event was reported.

Initial reporter phone: (b)(6).Customer claimed the cuff leaked during use.The investigation of the complaint was limited because no sample was returned; therefore, visual and functional testing could not be performed.During the manufacturing process the devices were 100% inflation tested, including inflating each device cuff and leaving it for a 12-hour period.Reductions in pressure over this time are considered a failure and the device would be rejected.Each cuff is also recommended for testing by the customer prior to use per the instructions for use.Due to fact that cuff leak was observed after placement, it is probable that the reported failure occurred during the tracheostomy procedure due to contact with sharp edges.Unfortunately, without the sample, the true root cause of this issue cannot be determined.A review of the device history records shows there were no observations recorded during manufacturing to suggest an issue of this nature would occur with this lot of products.Another one customer complaint was received against the affected lot number that describes the same issue but is not confirmed.There is no trend of confirmed complaints in relation with the identified issue.
