Claim 14:
15. A method for treating a patient for a respiratory condition, comprising,
providing a ventilator circuit including a ventilator unit, ventilator tubing, and a PPV mask with the elbow of claim 1 attached thereto;
placing the mask on the face of a patient and pressurizing the ventilator circuit to a ventilator pressure greater than 8 cm H2O, wherein the ventilator pressure in the ventilator circuit causes a seal to form between the mask and the face of the patient and biases the access valve of the elbow to the closed position, the ventilator unit further comprising bi-level ventilation that increases and decreases in pressure differing by at least 2 cm H2O;
inserting an appliance through the access valve of the elbow and into the mouth of the patient and removing the appliance, wherein upon removing the appliance from the access valve, the bias on the access valve causes the access valve to at least partially seal.
