Cannula apparatus for respiration therapy, having a pair of body members, each having a pair of cannulae for providing a cannula nipple outlet for each of a person\s nostrils, the two body members respectively delivering gas to each of the person\s nostrils, and monitoring the respiration of each of the person\s nostrils. One of the body members is carried inwardly of the other, its cannulae also carried inwardly of those of the other, achieving the patient comfort of only feeling a single cannula in each nostril, yet the gas and monitoring lumens and their outlets are separate for good operativity of respiration and breathing-monitoring. Interchangeability of the body members and their respective tubing is providing by operative equality of areas of the cylindrical and annular passages.
