Title:
AIRWAY-BASED CARDIAC OUTPUT MONITOR AND METHODS FOR USING SAME
Document Type and Number:
WIPO Patent Application WO2000067634
Kind Code:
A3
Abstract:
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.
