OG exemplary drawing
 
1. A positive pressure ventilation (PPV) elbow for accessing the oral cavity of a patient wearing a PPV mask under pressure, comprising:
a housing forming the elbow and defining an air supply conduit extending between an air supply inlet and an air supply outlet, the air supply conduit configured to deliver pressurized air from the inlet to the outlet;
a mask connector configured to attach to the positive pressure ventilation mask;
an access port formed through the housing into the conduit, the access port providing access to the mouth of a patient wearing the mask with the elbow connected thereto;
an access valve positioned in the port, the access valve movable between a closed position and an open position, the access valve configured to open to a diameter of at least 15 mm and configured to self-seal from a ventilator pressure in a range from 8-20 cm H2O, wherein the self-sealing is configured to occur from the ventilator pressure pushing the access valve to the closed position.
