This invention describes a method for processing pressure signals derivable from locations inside or outside a human or animal body or body cavity. Different aspects of the invention relate to a method for optimal differentiating between cardiac beat- and artifact-induced pressure waves, a method for obtaining new and improved information from said pressure signals, a method for obtaining signals predicting pressures inside a body or body cavity from pressure signals outside said body or body cavity. In particular, this invention describes a system for sensing continuous pressures signals and displaying output of processing according to the inventive methods.
