Standardized measurement of physiological pressures using an air-charged catheter apparatus

A system for providing a standardized pressure value representing a transient pressure event within a region of interest within a living body comprising:

• an air-charged catheter that records pressure data representing the region of interest;
• and
• a measurement assembly, comprising a processor and at least one non-transitory computer readable medium storing executable instructions executable by the processor, the measurement assembly calculates at least a peak pressure representing the transient pressure event and a time to peak pressure, representing the time necessary to reach the peak pressure, from the recorded pressure data and
• calculates the standardized pressure value, representing a peak pressure that would be expected for a water-filled catheter given the determined peak pressure, as a function of the peak pressure and the time to peak pressure;
• and
• a user interface that displays at least the standardized pressure value.
