Abstract:
1. A method for processing continuous pressure-related signals derivable from locations inside or outside a human body or body cavity, comprising the steps of obtaining samples of said signals at specific intervals, and using a processing unit for converting thus sampled pressure signals into pressure-related digital data with a time reference, wherein for selectable time sequence windows the method comprises using the processing unit for the further steps of: a) identifying from said digital data single pressure waves related to cardiac beat-induced pressure waves, b) identifying from said digital data pressure waves related to artifacts or a combination of artifacts and cardiac beat-induced pressure waves, c) computing time sequence (TS.x)-related parameters of said single pressure waves during individual of said time sequence windows, d) establishing an analysis output of said time sequence (TS.x)-related parameters for a selectable number of said time sequence windows, e) establishing a deliverable first control signal related to an analysis output in step d) for a selectable number of said time sequence windows, said first control signal being determined according to one or more selectable criteria for said analysis output, and f) modifying said deliverable first control signal into a second control signal to provide a performance modifying signal, wherein said identifying steps a) and b) prevent further analysis of the time sequence windows with delta time sequence (ΔTS.x)-related parameters outside of the selected criteria for thresholds and ranges of said delta time sequence (ΔTS.x)-related parameters, said delta time sequence (ΔTS.x)-related parameters selected from one or more of:
