A single use, disposable, oxygen mask having an integral mouthguard/bite-block, and an oxygen intake port having a right angle is placed centrally on a side of the mask along with a right angle port to facilitate an endoscopic procedure. A patient biting down on the bite-block portion of the mouthguard keeps the mask in place. The mask has a concave shaped body that fits over and around the nose and mouth of the patient. An exhaler side port is provided on an opposite side of the mask.
