1. A method for providing a relative value of mean arterial pressure of a subject comprising the steps of:
- A. measuring tissue moisture at a selected area of perfused tissue of the subject, B. acquiring data samples of the measured moisture content at the selected area, and C. converting the collected data to a value of mean arterial pressure.

Abstract
Relative Mean Arterial Pressure values are obtained non-invasively using a probe to obtain moisture measurements at a selected site on a subject. A control collects data samples. A converter produces a relative value of Mean Arterial Pressure (MAP) in response to the collected data (DPM) in accordance with a correlation defined by:
MAP=(DPM−DPM(0))/K(I)
