A system for applying a controlled atmosphere for breathing by a patient, in the treatment of croup or the like, includes a head piece which has a portion extending over the temple, a portion extending over the top of the head in the form of adjustable straps, and an elastic strap extending behind the head. A front support frame is connected to the head piece, and a U-shaped flexible gas delivery tube is supported on the frame. Nebulized oxygen enriched fog may be delivered from a nebulizer to the tube and emitted through orifices formed on an inside surface of the tube, at the ascending portions near the corners of the horizontal bottom portion, to form streams which are directed toward each other and which coalesce at a region in front of the face and mouth of the patient, for breathing by the patient. The support frame is pivotally mounted on the headgear so that it may be moved from its normal lowered position to a raised position to move the delivery tube out of the patient\s way for eating and drinking.

Apparatus adapted to be supported on the head of a patient for controllably supplying gas from a source of gas under low pressure to the mouth and nose region of the patient for breathing by the patient, comprising: a head piece having lateral side members adapted to extend around the patient\s head and transverse members connected to said lateral members and proportioned to extend transversely of the head over the top and along the sides of the head and means for joining said transverse members at the top of the patient\s head, a frontal support frame having a generally U-shaped bottom and a pair of side arms connected to the free ends thereof, respectively, means for connecting said side arms to said head piece at said lateral side members thereof with said bottom of said support frame adapted to be received below the chin of the patient, a flexible gas delivery tube for delivery of gas from the source of gas to the patient having a remote open end adapted for connection to the source of gas and an open end opposite said remote end, means for supporting a portion of said gas delivery tube on said frontal support frame such that the tube extends continuously along said frame side arms and said bottom, thereby defining a descending section of said tube extending from said remote end along one of said side arms, a transverse section thereof extending along said bottom, and terminating in an ascending section thereof extending along the other side arm leading to said opposite open end, means for closing the opposite open end of said tube above said ascending section thereof, and orifice means formed in said tube at the transitions between said descending and ascending tube sections and said transverse tube section, said orifice means being positioned in said delivery tube to direct generally lateral intersecting streams of the gas therefrom at a common region generally forward of the nose and mouth of the patient and avoiding direct impingement of said streams against the nose and mouth to provide a coalescing gas region immediately forward of the nose and mouth of the patient for breathing by the patient.
