Hemodynamic waveform-based diagnosis and treatment
First Claim
1. A method of monitoring pressure within a medical patient, comprising:
- measuring an actual pressure in a medical patient in a first time period;
measuring an indicator of said actual pressure in the first time period, wherein said indicator is derived from an electrical signal of the patient'"'"'s heart;
determining a correlative relationship between the actual pressure and the indicator, wherein both the actual pressure and the indicator are obtained in the first time period;
measuring the indicator in a second time period; and
determining the actual pressure in said second time period based on the correlative relationship obtained in said first time period and the indicator obtained in said second time period.

Abstract
A method of monitoring pressure within a medical patient, includes measuring an actual pressure in a medical patient in a first time period; measuring an indicator of the actual pressure in the first time period, wherein the indicator is derived from an electrical signal of the patient'"'"'s heart; determining a correlative relationship between the actual pressure and the indicator, wherein both the actual pressure and the indicator are obtained in the first time period; measuring the indicator in a second time period; and determining the actual pressure in the second time period based on the correlative relationship obtained in the first time period and the indicator obtained in the second time period.

6. A method of monitoring pressure within a medical patient, comprising:
-
measuring an indicator of a pressure within a medical patient, wherein the indicator is related to an electrical signal generated by a patient;
determining the pressure based at least in part upon the indicator and a pre-determined relationship between the pressure and the indicator, wherein the pre-determined relationship is determined from historical pressure data and historical indicator data of the patient; and
providing an indication of the pressure. - View Dependent Claims (7)

8. A method of calibrating a pressure monitoring system, comprising:
-
measuring an actual pressure within the heart of a medical patient with a pressure monitoring system;
measuring an indicator of the actual pressure, wherein said indicator is related to a physiological parameter of the medical patient;
calculating a pressure value indicative of the actual pressure based at least in part upon the indicator of the actual pressure and a pre-determined relationship between the actual pressure and the indicator of the actual pressure, wherein the pre-determined relationship is determined from historical pressure data and historical indicator data of the patient;
determining an error value based upon the difference between the measured actual pressure and the calculated pressure value; and
calibrating the pressure monitoring system when the error value exceeds a predetermined threshold. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A method of controlling delivery of a therapy delivered to a patient, comprising:
-
measuring an indicator of an actual pressure within a medical patient, wherein the indicator corresponds to a physiological parameter of the medical patient;
determining the actual pressure based at least in part upon the indicator and a pre-determined relationship between the actual pressure and the indicator, wherein the pre-determined relationship comprises a neural network trained with historical pressure data and historical indicator data; and
controlling a therapy based upon the determined pressure. - View Dependent Claims (17, 18, 19, 20, 21, 22)
