<p>The invention relates to a nasopharyngeal or oropharyngeal cannula (1, 10) comprising a body (2, 20) formed by a tube (4, 40) extending through a collar (3, 30) which can rest on the outer edges of a buccal or nasal cavity of a patient, said tube comprising a first portion (43, 430) that is at least partially curved so as to be inserted into the patient's buccal or nasal cavity as far as the pharynx and a main channel (5, 50) forming a fluid passage between the two ends (41, 42; 410, 420) of the tube. The tube comprises a hard second portion (44, 440) disposed on one side of the collar opposite the first portion, said second portion comprising a notch (E) transverse to the axis of the main channel and configured to receive infrared means that can obtain a capnography measurement of the air exhaled through the main channel.</p> |
