A respiratory gas analyzer (10) for measuring the cardiac output of a subject includes a flow meter (14) and an oxygen sensor (16) interconnected with one another between a mouthpiece (12) and a source of respiratory gases which may be a controlled source or the atmosphere. An oximeter (26) provides measurements of the oxygen saturation of the subject. A computer connected to receive the signals from the flow meter (14), oxygen sensor (16), and oximeter (26) can then calculate the subject's cardiac output.

L'invention concerne un analyseur du gaz respiratoire (10) servant à mesurer le débit cardiaque d'un sujet, comprenant un débitmètre (14) et un détecteur d'oxygène (16) interconnectés l'un à l'autre placés entre une pièce buccale (12) et une source de gaz respiratoires qui peut être une source régulée ou de l'air. Un oxymètre (26) produit des mesures de la saturation en oxygène du sujet. Un ordinateur connecté pour recevoir les signaux du débitmètre (14), du détecteur d'oxygène (16) et de l'oxymètre (26) peut alors calculer le débit cardiaque du sujet.
