Air-impingement Manipulation to Clear Subglottic Secretion to Prevent VAP in Prolonged Intubated Patients

Ventilator-associated pneumonia (VAP) is the most frequent infection occurring in patients who are admitted to the ICU. The accumulation of respiratory secretions in the subglottic space is a well-proven cause of VAP. Investigators invented a manual method with high-flow air produced by resuscitator to impinge secretion from the subglottic space to oral cavity. Investigators want to compare it with conventional method which uses a special intubation tube with an independent dorsal lumen to suction subglottic secretion.
