METHOD AND APPARATUS FOR MEASURING CONTINUOUS BLOOD FLOW AT LOW POWER

摘要

A technique for determining blood flow in a living body by changing the thermal energy level by a predetermined amount at a site in a blood flow path and detecting temperatures at locations upstream and downstream of the site. The temperature difference at such locations is determined and the blood flow is calculated as a function of the change in energy level and of the temperature difference measured prior to and following the change in energy level.
