摘要

The ideal range for tracheal tube cuff pressures is usually taken to be between 20 to 30 cm H2O.This is easily measured with a cuff pressure manometer and should be measured in each instance.The importance of tracheal tube cuff pressures is highlighted by the spectrum of airway complications that can occur with incorrect cuff pressures.High cuff pressures can result in complications ranging from sore throat and hoarseness to tracheal stenosis,necrosis,and even rupture.In such cases,the postulated causative factor is diminished blood flow to tracheal mucosa due to excessive cuff pressure on the tracheal wall.This hypothesized ischemic injury then produces healing fibrosis months or even years later.On the other hand,cuff pressures that are too low place the patient at risk for aspiration of gastric contents and consequently,aspiration pneumonitis and pneumonia.This is why the authors recommend that cuff pressures be measured following all intubations.
