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.
Claims13
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 by electronic hardware, 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.
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 the patient;
- determining by electronic hardware 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.
