Abstract: 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.

Abstract: A filtering face mask that covers at least the nose and mouth of a wearer and that includes an exhalation valve. The exhalation valve opens in response to increased pressure when the wearer exhales to allow the exhaled air to be rapidly purged from the mask interior.
