A system and method for measuring the transpirational characteristics of a permeable polymeric membrane, particularly polymeric membranes used for bandages. The polymeric membrane is placed against a moisture source. A probe is applied to the other side. Signals from the probe are sampled at a high rate to detect a first transient appearance of moisture on the surface being measured. The interval between the first transient response and a predetermined equilibrium value defines the transpirational characteristics of the polymeric membrane.

Method and apparatus for determining transpiration characteristics of a permeable membrane

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:=((0))/().

Method and apparatus for monitoring the efficacy of fluid resuscitation

A method and apparatus for measuring relative hydration of a substrate. Measurements of the electrical characteristics of the substrate and the force applied to and the temperature of the substrate during the measurement provide inputs for determining such relative hydration of the substrate.
