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