We wish to report two issues that we recently identified following the insertion of a Bivona® (Smiths Medical, Ashford, UK) tracheostomy tube which developed recurrent leakage due to cuff deflation. In the first instance, the pilot balloon and cuff were both slowly deflating and required repeated re-inflation. In the second instance (with the same tube), the pilot balloon pressure was elevated, but the cuff continued to have a sizeable leak. On removal and examination of the tube, no structural damage was noted, but the cause for both incidents was identified.

The Bivona tracheostomy tube was surgically inserted, and the cuff balloon was initially inflated with air and a good seal was achieved. However, we found a gradual and consistent loss of cuff pressure leading to a loss of tidal volume. The cuff was then re-inflated with air via the pilot balloon and although this resolved the is...
