Abstract
Physiological changes in a patient's circulatory system can be detected in real time during open heart surgery by injecting a known amount of a marker substance into the patient's blood prior to surgery, and during surgery continuously concurrently monitoring variations both of the quantity of circulatory fluid in the heart-lung machine's reservoir and of the marker substance concentration in the fluid being pumped through the heart-lung machine. The patient's blood volume can also be continuously computed from the data thus gathered.
