Clear tubing. ); and patients with known anatomical laryngeo-tracheal abnormalities were excluded from this study. Novel ETT cuffs made of polyurethane,158 silicone, 159 and latex 160 have been developed and . Use of Tracheostomy Tube Cuff | Iowa Head and Neck Protocols D) Pressure gauge attached to pilot balloon of defective cuff with reading of 30 mmHg with cuff not appropriately inflated. Although it varied considerably, the amount of air required to achieve a cuff pressure of 20 cmH2O was similar with each tube size. Decrease the cuff pressure to 30 cm H2O by withdrawing a small amount of air from the balloon with a 10 mL syringe. As newer manufacturing techniques have decreased the occurrence of ETT defects, routine assessments of the ETT cuff integrity prior to use have become increasingly less common among providers. ETT cuff pressures would be measured with a cuff manometer following estimation by either the PBP method or the LOR method. Another viable argument is to employ a more pragmatic solution to prevent overly high cuff pressures by inflating the cuff until no air leak is detected by auscultation. How much air is injected into the cuff is not a major concern for almost all anaesthetists and they usually depend on palpating the external cuff tense to judge is it too much, accurate or not enough?
