PROCESSING OF CONTINUOUS PRESSURE-RELATED SIGNALS DERIVABLE FROM A HUMAN OR ANIMAL BODY OR BODY CAVITY: METHODS, DEVICES AND SYSTEMS

A method for processing pressure signals derived from locations inside or outside a human or animal body or body cavity. Different aspects relate to a method for optimal differentiating between cardiac beat- and artifact-induced pressure waves, a method for obtaining new and improved information from the pressure signals, and methods for predicting pressures inside a body or body cavity from pressure-related signals derivable from outside the body or body cavity. Devices and a system for sensing continuous pressures signals and displaying output of processing according to method. Other features related to aspects of draining fluid from a brain or spinal fluid cavity.
