A nasal cannula arrangement for use as part of systems for delivery respiratory gases to a patient is disclosed. The nasal cannula arrangement includes a manifold part adapted to receive gases from a delivery conduit. The manifold includes one but preferably a pair of prongs extending upward and curving towards the rear of the manifold. The prongs are inserted into the nostrils of the patient and deliver gases to a patient. The prongs have a cut out on the rear side of the prongs. The cut out forms a gases outlet in the prongs and are shaped such that the area of the cut out area is greater than the cross sectional area of the prongs at the entry point to the prongs.

Nasal cannula

Medical breathing tubes have a tubular body that defines a lumen extending between open terminal ends of the tubular body. An internal form is enclosed within the lumen and supportive of the tubular body. The internal form may be a coated encapsulated internal form where the coating secures the internal form to the tubular body. The internal form may provide for a series of alternative crests and troughs of the tubular body. A patient interface and/or a securement system may be attached to the tubular body.
