Purpose of trachea cuff
WebPurpose: To determine the effects of deflating the tracheal cuff during disconnections from mechanical ventilation (MV) in tracheostomized patients. Methods: This was a single-center, randomized trial conducted in a general ICU of a tertiary hospital with regional referral for trauma patients. Patients at high risk of aspiration based on the drink test were excluded. WebJun 1, 2014 · The standard HVLP PVC cuff is designed to inflate to 1.5–2 times the size of the normal trachea. 70 In doing so, the cuff presumably will conform to the tracheal wall size, provide an air seal during inspiration, and prevent gross fluid leakage during expiration at safe tracheal wall pressures.

WebJun 18, 2015 · The change to low-pressure high-volume cuffs has resulted in a cuff which is incompletely expanded, forming folds against the walls of the trachea. These folds are perfect entry points for supraglottic slime.

The criteria included: 1. medical stability. 2. respiratory stability. 3. fraction of inspired oxygen ≤ 0.4. 4. tracheal suction ≤ 1-2 hourly. 5. sputum thin and easy to suction. 6. sputum clear or white. 7. ≥moderate cough strength.
WebDec 17, 2004 · Ideally, patients at risk of developing laryngeal edema should be identified as early as possible, and the cuff-leak test has been proposed for this purpose. The principle of this test is quite simple and is based on the fact that the air leak around a tracheal tube with a cuff deflated will be inversely related to the degree of laryngeal obstruction generated by …
