Abstract:
Devices, systems, and methods for monitoring patient hemodynamic status, systemic vascular resistance, reversal of cardiac and respiratory rates, and patient respiratory volume or effort are disclosed. A peripheral venous pressure is measured and used to detect levels, changes, or problems relating to patient blood volume. The peripheral venous pressure measurement is transformed from the time domain to the frequency domain for analysis. A heart rate frequency is identified, and harmonics of the heart rate frequency are detected and evaluated to determine, among other things, hypovolemia or hypervolemia, systemic vascular resistance, and of cardiac and respiratory rates, and patient respiratory volume or effort.

Claim (Index 15):
A method of measuring and evaluating blood volume of a patient using a measurement associated with a peripheral venous pressure (PVP) within a peripheral vein of a circulatory system of the patient, comprising:\n monitoring, by a transducer of a PVP sensor, a physical phenomenon associated with the PVP within the peripheral vein of the circulatory system of the patient; generating, by the PVP sensor, an electronic signal associated with the PVP over a sample period, the values of the electronic signal over the sample period forming a time-domain PVP signal; applying, by a processor of an evaluation unit, a transformation to the time-domain PVP signal to generate a frequency-domain PVP signal; identifying, by the processor of the evaluation unit, a plurality of frequencies associated with local maxima of the frequency-domain PVP signal, including a heart rate frequency (F 1 ), a first harmonic frequency (F 2 ) of the heart rate frequency, and a second harmonic frequency (F 3 ) of the heart rate frequency; and calculating, by the processor of the evaluation unit, a blood volume metric based at least in part upon the heart rate frequency (F 1 ), the first harmonic frequency (F 2 ), and the second harmonic frequency (F 3 ).
