The suspect tracheostomy tube was returned without its packaging for product inspection.Visual inspection observed no abnormalities or non-conformities.During functional testing, the cuff was inflated with air and the device submerged in water.No bubbles, suggesting a leak, were observed coming from the device.The tracheostomy tube, with pressurized cuff, was then left to rest for 12 hours.After the 12 hours, the device was inspected.No cuff reduction was observed; the cuff remained fully pressurized.The reported product issue could not be duplicated during product evaluation.As the returned product was confirmed to operate as intended, the reported product fault could not be confirmed.No corrective actions are planned at this time.
