Tracheal wall pressures in the clinical setting: comparing Portex Soft Seal and Lotrach cuffs

The tracheal wall pressure (TWP) exerted by a tracheal tube cuff should normally be kept between 20 and 30 cmH 2 O. This protects against mucosal injury whilst allowing ventilation without an audible air leak [ 1 ]. The Portex Soft Seal high-volume low-pressure (HVLP) cuff has a working intracuff pr... View More
