A respiratory apparatus is provided including a liquid ventilator. The primary components of the apparatus include a ventilator, control valve, and chiller/oxygenator. The invention utilizes a closed loop circulation of a breathable liquid to provide liquid ventilation and pulmonary cooling. The ventilator is a dual-chambered device which may be hand or machine actuated. A dual compression force is applied to the ventilator which induces a patient's inspiration of oxygenated and cooled liquid from an inspiration chamber, and simultaneously induces transfer of oxygen depleted, heated liquid into the oxygenator/chiller from an expiration chamber. Upon release of the compression force, the ventilator returns to its normally open or uncompressed state inducing evacuation of the liquid from the patient's lungs into the expiration chamber and flow of re-oxygenated and chilled liquid into the inspiration chamber of the ventilator, thus readying the ventilator for the next inspiration phase.
