ABSTRACT:
An improved nasopharyngeal airway simultaneously maintains patency of the breathing passage while providing continuous oxygenation to the back of the oropharynx region of a conscious or unconscious patient through at least one unobstructed integral lumen extending the length of and adjacent the airway. Additional medical procedures can be performed through the airway during constant oxygenation without discontinuous or reducing oxygenation and without causing tissue trauma which would otherwise occur but for the guidance and protection of the airway.
