An apparatus and method for preventing contamination of the Post Anesthesia Care Unit of A Hospital by the use of a mask sealed to the patient's face and connected by a ventilator circuit to an airator that pulls a vacuum to exhaust the patient's expirations to the outside atmosphere. The disclosure also includes a 'oxyvent' which is a tube adapted to be attached to an oxygen tank and to a patient to provide a higher oxygen ratio to the patient and to provide forced ventilation to a patient who has difficulty ventilating.
