Method for determining relationships between different pressure-related signals derivable from a human or animal body or body cavity

A method for processing two or more simultaneous continuous pressure-related signals derivable from a human or animal body from one or more locations thereof electable from:

• inside the body, outside the body, inside body cavity, outside body cavity, comprising the steps of obtaining samples of said signals at specific intervals, and converting thus sampled pressure signals into pressure-related digital data with identical time reference,
• wherein for selectable and simultaneous time sequence windows the method comprises the further steps of:
• a) identifying from said digital data single pressure waves related to cardiac beat-induced pressure waves within said two or more simultaneous signals constituting a pressure recording,
• b) identifying from said digital data pressure waves related to artifacts or a combination of artifacts and cardiac beat-induced pressure waves within said two or more simultaneous signals constituting a pressure recording,
• c) computing time sequence (TS.x)-related parameters of said single pressure waves during said identical time sequence windows within said two or more simultaneous signals constituting a pressure recording,
• wherein the method comprising the further steps of:
• d) determining relationships between time sequence (TS.x)-related parameters of said identical time sequence windows within said two or more simultaneous signals constituting a pressure recording,
• said relationships calculated as related time sequence (rTS.x) parameters, and
• e) determining said related time sequence (rTS.x) parameters for a selectable number of recordings,
• said related time sequence (rTS.x) parameters to be used for formula-based adjustments of time sequence (TS.x)-related parameters of individual pressure-related signals.
