METHOD AND APPARATUS FOR MONITORING BLOOD CONDITION AND CARDIOPULMONARY FUNCTION

摘要

Sensors located on an implantable sensor section (22) are placed adjacent one or more of a surgical patient's major thoracic blood-containing structures such as the aorta or pulmonary artery, and characteristics of blood in the blood-containing structures are determined non-invasively by measuring transmission or reflection of light or other types of energy by the blood. Emitters and receptors included in the sensors are connected electrically with suitable electronic signal generating (40) and processing components (26) in a package remote (20) from the implantable sensor section (22).
