Domestic and foreign studies show that after tracheal intubation, the retentate on the cuff is an important source of VPA pathogens. The basic function of the cuff on the tracheal cannula is to prevent air leakage and aspiration, if the pressure of the cuff is too low, the cuff is not enough to seal the airway, and pathogenic bacteria of the upper respiratory tract are easy to be aspirated into the lower respiratory tract; however, if the cuff is inflated too much, the capillaries of the airway mucosa can be damaged, and tracheoesophageal fistula can even occur. Therefore, the guidelines for diagnosis, prevention and treatment of the ventilator-associated pneumonia of the Severe medical society of Chinese medical society (2013) and the consensus draft of the artificial airway air bag management experts of the respiratory therapy group of the Chinese medical society of respiratory disease (2014) all suggest that the cuff pressure is maintained at 25-30 cm H20（1 cm H20=0.098 kpa). Therefore, managing the cuff pressure on the endotracheal tube is one of the important means to reduce the incidence of VPA.
