Abstract
A method of blood flow monitoring for a patient, the method comprising the steps of: a) receiving a first signal indicative of the real time cardiac output for the patient; b) processing the continuous wave Doppler signal to provide an estimate of blood flow velocity as a function of time; c) receiving a pressure measurement indicative of the blood flow resistance through the patient; and d) calculating an Inotropy measure indicative of the potential and kinetic energy of the cardiac output of the patient.

A method of blood flow monitoring for a patient, said method comprising the steps of:
- a) receiving a first signal indicative of the real time cardiac output for said patient;
- b) processing said first signal to provide an estimate of blood flow velocity as a function of time;
- c) receiving a pressure measurement indicative of the blood flow resistance through the patient;
- and
- d) calculating an Inotropy measure indicative of the potential and kinetic energy of the cardiac output of the patient.
A system to monitor blood flowing in a patient, said system comprising:
- first sampling unit for sampling a signal indicative of the cardiac output from the patient;
- second sampling unit for sampling a signal indicative of the arterial pressure of the patient;
- a processor interconnected to the first and second sampling unit and adapted to calculate an Inotropy measure indicative of the potential and kinetic energy of the cardiac output of the patient from said signal indicative of the cardiac output and signal indicative of the arterial pressure.
A computer-readable carrier medium carrying a set of instructions that when executed by one or more processors cause the one or more processors to carry out a method of blood flow monitoring for a patient, said method comprising the steps of:
- (a) receiving a continuous wave Doppler signal indicative of blood flowing in said patient;
- (b) receiving a pressure signal indicative of the blood pressure flowing in said patient;
- and
- (c) processing said continuous wave Doppler signal and pressure signal to provide a potential and kinetic energy measure as a function of time.
A method of calculating the blood flow myocardial power or inotropy of a patient, the method including the steps of:
- a) receiving a continuous wave Doppler signal indicative of blood flowing in said patient;
- b) processing said continuous wave Doppler signal to provide an estimate of blood flow velocity as a function of time;
- and
- c) receiving a second signal indicative of the pressure of blood flowing through the body of the patient;
- d) combining said two signals to produce an inotropy measure of the potential and kinetic energy developed by the heart.
