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.
