ABSTRACT:
An oral airway for providing an air passage to a patient's trachea. The oral airway includes a curved section and a straight section with the curved section having spaced-apart curved upper and lower members and the straight section having spaced-apart planar upper and lower members with the same width. The curved upper member has the same width as the planar upper member with the curved lower member having a greater width than the width of the lower planar member. The width of the curved lower member is greater than the width of the planar lower member and the distance between the curved upper and lower members is greater than the distance between the planar upper and lower members. The curved lower member has a generally inverted V-shaped cross-section.
