The present invention is a convenient and inexpensive strap for securely and comfortably holding a nasal cannula to the head of a wearer. Typically the strap is made of a soft cloth or foam fabric, about 1/8-3/4 inch wide and 6-16 inches long. Preferably the strap has strips of both hook and loop fasteners about 1/2-3 inches long at each end on one same side of the cloth. To use the strap, one end of it is looped around one of the oxygen tubes and secured to itself. The strap extends behind the ears of the wearer, and rests on the back of the head or the nape of the neck of the wearer. Then, the other end of the strap is looped around the other oxygen tube and secured to itself. The tension in the strap may be adjusted to pull the tubes in slightly towards the middle of the back of the head or neck, which may also pull the tubes off of the back of the ears. This way, the cannula may be conveniently, securely, and comfortably attached to the head of the wearer. This securement reduces the tendency of the tubes to move relative to the users skin and ears, and therefore, without lifting the tubes up off the ears, it may reduce chafing of the skin and ears. Also, the invented strap requires no additional cap, harness, or head-encircling strap, and so it is not psychologically or physically burdensome.

1. A cannula securement system consisting only of an air delivery system and a single elongated cannula strap; the air delivery system having a front, a rear, a top and a bottom, and consisting of: a nosepiece at the front of the air delivery system for extending into a user's nostrils and for being in fluid communication with the user's nostrils; and a hollow left cannula tube and a hollow right cannula tube extending rearward from the nosepiece and curving downward to form a left loop and a right loop at the rear of the air delivery system for draping over a user's left ear and for draping over a user's right ear, respectively, and the hollow left cannula tube and hollow right cannula tube further extending forward from the left loop and right loop for extending over the user's left and right shoulders, respectively, and coming together at a location below the nosepiece for crossing forward over a user's shoulders to the user's chest, wherein the hollow left cannula tube and hollow right cannula tube are in fluid communication with the nosepiece and are supplied with an oxygen-rich gas to provide oxygen-rich gas to the nosepiece; and wherein the single elongated cannula strap has a center area and two distal ends; wherein said two distal ends are attached to lower regions of said left loop and a lower region of said right loop; wherein said cannula strap extends rearward from said lower regions of the left loop and said right loop with the two distal ends being the upward-most portion of the cannula strap; wherein the single cannula strap comprises an adjustable fastener adapted to shorten, and thereby tension, the cannula strap, so that the cannula strap pulls the left loop and right loop rearward and does not lift the left loop and right loop upwards. 2. The system as in claim 1, wherein said strap is flat, and has a first surface, and a second surface, wherein said adjustable fastener of each distal end comprises a hook patch and a loop patch of hook and loop fastener on the first surface, and wherein the second surface has no hook patches and no loop patches. 3. The system as in claim 2, wherein the hook patches and the loop patches are closely adjacent to each other with no space in between.
