Closed suction system is a multiple use design effective in decreasing the infection of lower respiratory tract infection and can reduce the mortality rate of nosocomial pneumonia.

It is designed for removal of bronchial secretions in intubated patients if they are on mechanical ventilation. The system allows the attending health professional to suction the patient tracheobronchial secretions without disconnecting the ventilator.

It is recommended to change the catheter in order to reduce the incidence of ventilator associated pneumonia (VAP).
