closed suction

, closed suctioningThe incorporation of a suction system into a mechanical ventilator that permits airway suctioning without disconnecting patients from the ventilator. Closed suctioning prevents loss of PEEP and loss of alveolar volume, and decreases contamination of the airway or the ventilator circuit by gases, germs, liquids, or fomites in the intensive care unit.
