ABSTRACT:
(1) An apparatus for delivering inhalant and monitoring exhaled fluid; (2) a method of making same; and (3) a method of delivering inhalant and monitoring exhaled fluid are disclosed. The apparatus for delivering inhalant to and monitoring exhaled fluid from a patient includes a first cannula having a distal end adapted to be received at a first depth in, for delivering a fluid into, a nostril of the patient, and a second cannula having a distal end adapted to be received at a second depth in, for sampling exhaled fluid from, the nostril. The method of making an apparatus for delivering inhalant and monitoring exhaled fluid involves modifying an apparatus, including a first cannula connected for delivering fluid to a nasal cannula, and a second cannula connected to, for drawing fluid from, the nasal cannula, which includes disconnecting the nasal cannula from the first cannula, thereby defining a first truncated end, disconnecting the nasal cannula from the second cannula, thereby defining a second truncated end, and providing one or both of the first truncated end and the second truncated end with: an aperture, a perforated zone, a rounded contour, an anesthetic coating or combinations thereof. The method of delivering inhalant to and monitoring exhaled fluid from a patient includes inserting to a first depth a distal end of a first cannula in, for delivering a fluid into, a nostril of the patient, and inserting to a second depth a distal end of a second cannula in, for sampling exhaled fluid from, the nostril.
