system and method for monitoring and determining patient parameters from detected venous waveform

摘要

The present invention relates to devices, systems and methods for monitoring a patient's hemodynamic state, systemic vascular resistance, reversal of cardiac and respiratory rates, and patient's respiratory volume or exertion. A peripheral venous pressure is measured and used to detect levels, changes, or problems with the patient's blood volume. peripheral venous pressure measurement is transformed from time domain to frequency domain for analysis. a heart rate is identified, and heart rate harmonics are detected and evaluated to determine, among other things, hypovolemia or hypervolemia, systemic vascular resistance, and cardiac and respiratory rates, and the patient's volume or respiratory effort.
