Claim 7:
8. A non-transitory computer readable medium storing machine executable instructions for providing a standardized pressure value from pressure data representing a transient pressure event within a region of interest within a living body collected with an air-charger catheter, the machine executable instructions being executable by an associated processor to perform a method comprising:
determining at least a peak pressure, Ppeak, representing a maximum recorded pressure, in centimeters of water, in the pressure data collected with the air-charged catheter during the transient pressure event and a time to peak pressure, TPP, representing a time necessary to reach the peak pressure at the air-charged catheter, from the pressure data collected with the air-charged catheter; and
calculating the standardized pressure value, PStd, representing a peak pressure that would be expected for a water-filled catheter given the peak pressure determined from the pressure data collected with the air-charged catheter, such that:, P
    Std
