percutaneous transtracheal ventilation


Also found in: Acronyms.

percutaneous transtracheal ventilation

an emergency procedure that delivers oxygen under sufficient pressure through a cricothyrotomy to sustain a patient's oxygenation temporarily until a definitive surgical airway can be established. This procedure is by definition palliative because of the suboptimal lumen of the ventilatory tube (an intravenous catheter) and requires 50 psi of pressure at the source of oxygen delivery.

percutaneous transtracheal ventilation

An emergency, life-saving means of providing an oxygen supply using a 16 gauge plastic catheter sheathed needle and positive pressure ventilation. The catheter needle is passed directly through the skin in the middle of the front of the neck until the catheter is in the windpipe. The needle is then withdrawn and the positive pressure machine connected to the catheter.
