negative pressure ventilation

negative pressure ventilation
a type of mechanical ventilation in which negative pressure is generated on the outside of the patient's chest and transmitted to the interior of the thorax in order to expand the lungs and allow air to flow in; used primarily with patients having extreme weakness or paralysis of the chest muscles. See also negative pressure ventilator, under ventilator.
