Detailed explanation-1: -The ETT cuff pressure associated with impaired tracheal capillary perfusion ranges between 30 and 50 cm H2O. Sustained overinflation of the ETT cuff increases the risk for tracheal damage: subglottic stenosis or scarring, 14, 15 hoarseness, 16, 17 nerve damage, 18 fistula, 19 and damage of the tracheal wall.
Detailed explanation-2: -Cuff pressures greater than 30 cmH2O impede mucosal capillary blood flow. Multiple prior studies have recommended 30 cmH2O as the maximum safe cuff inflation pressure.
Detailed explanation-3: -Studies have shown that using too small of a blood pressure cuff can cause a patient’s systolic blood pressure measurement to increase 10 to 40 mmHg. Blood Pressure Cuff Used Over Clothing1, 3, 4-When having your blood pressure measured, the cuff should always be placed directly on your arm.
