Background

Ventilator-associated pneumonia (VAP), which refers to pneumonia occurring in intubated or tracheotomized patients after 48h of mechanical ventilation, is the most common hospital-acquired infection of the ICU. VAP results in prolonged mechanical ventilation, hospitalization, increased medical costs and increased risk of death. One of the pathogenesis of VAP is that oral secretions containing a large number of colonizing bacteria enter the lower respiratory tract through the gap between the artificial airway balloon and the tracheal wall, multiply in the lungs and cause invasive lesions. The subglottic suction can effectively drain the secretions on the air bag and reduce the retention of the secretions, thereby being an important measure for reducing the incidence rate of VAP.
