摘要
A nasal cannulae and a method is described for insufflating a treating gas into one nostril of an unintubated, conscious, spontaneously breathing patient having local or regional anesthesia administered thereto or recovering from residual general anesthesia while accurately and reliably measuring at least one gaseous component of exhaled breath in the other nostril enabling adaption of treatment to the state of the body functions of the patient. The cannulae (10, 10', 40) includes a hollow body (12, 12', 43) divided by a wall member (18, 18', 52) into inhalation (20, 44) and exhalation (22, 54) manifolds which are connected to an oxygen flow regulating device (24) and breathing gas analyzer (26), respectively. Hollow nasal prongs of same (14, 16, 46) or different lengths (14', 15') and adapted to be received in corresponding nostrils communicate with the manifolds (20, 44, 22, 54), respectively. The wall member may be integrally molded (18) with the body (12) or a conventional cannulae may be modified by insertion of a wall member (48', 52).
