Uncuffed ETT: Max leak pressure

Physics, Monitoring, & Devices

Uncuffed ETT are generally used on children 6 years old or younger. But should you ever used an uncuffed tube?

Weiss et al. did not look long term and no one can tell if cuffed tubes increase the risk of trachael stenosis in the long run. Historically, with low-volume, high pressure cuffs that was true. Adult, retrospective, and animal data suggest that cuff pressures less than 20 cm H20 in modern tubes are safe.
