摘要：
An embodiment of the disclosure provides a method for measuring change in blood volume using a transcutaneous measurement system applied to a patient's skin. The method involves placing a sensor in contact with the skin of a patient, where the sensor includes a light emitter and a photodetector. An intensity of light emanating from the light emitter is set and an initial intensity of light received at the photodetector is determined, where the light received at the photodetector has traveled through the patient's tissue. A later determination is then made of the intensity of the light received at the photodetector. A change in the blood volume is determined based on the intensity of the light emanating from the light emitter, the initial intensity of light received at the photodetector and the final intensity of light received at the photodetector.
