A respiratory mask for delivery of pressurized gas to a patient. The respiratory mask has a rigid shield and an elastic cushion surrounding the shield, the cushion being configured to conform to facial contours of a patient. A port is provided in the cushion, the port being configured to receive an implement inserted into the port and to provide a substantially gas-tight seal about the periphery of an implement received in the port. The port may be located in an area of the cushion that allows for a relatively direct route to the nares of the patient of the patient to allow insertion of the NG tube into the patients nares. Embodiments may include the port being a slit in the elastic cushion.
