Abstract
An improved nasal cannula is made of a soft pliable material and has two hollow tubular prongs which are ribbed to prevent significant closure of the airways through the prongs upon bending of the prongs and a base adapted to receive a soft strip of foam-like material which can be attached to a skull cap for securing the prongs of the cannula in the nasal passages of a patient.
