METHOD AND DEVICE FOR DETERMINING THE PERFUSION OF BLOOD IN A BODY MEMBER

摘要

The invention relates to a method and device for determining the perfusion of blood in a body member. Furthermore, the invention relates to a computer program for determining the perfusion of blood in a body member. To provide a technique to ensure that the actual patient perfusion condition does correlate with the calculated perfusion index value over a broad variety of patient conditions, a new method of determining the perfusion of blood in a body member is suggested, the method comprising the steps of: producing electrical measuring signals from a non¬ invasive photometric measuring process, normalizing the electrical measuring signals and determining a perfusion index from the normalized signals, using an energy value of at least one signal pulse.
