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.

Abstract: Devices, systems, and methods for filtering medical device noise artifacts from circulatory waveform signals are disclosed. A circulatory pressure is measured and transformed from the time domain to the frequency domain for analysis to determine patient status. To avoid artifacts of the pumping, the time-domain measurements are filtered to generate a filtered time-domain signal, by removing active pumping periods. The filtered time-domain signal is transformed into a frequency-domain signal, which is analyzed based upon peaks indicating respiratory rate, heart rate, or harmonics thereof. Peaks may be adjusted based on a ratio that considers removed signals. A metric of patient status is then determined from the peaks or corresponding frequencies. The patient status may be related to blood volume of the patient and may be used to control pump operation.

Abstract: Devices, systems, and methods for filtering medical device noise artifacts from venous waveform signals are disclosed. A peripheral venous pressure (PVP) is measured and transformed from the time domain to the frequency domain for analysis to determine patient status. To avoid artifacts of the pumping, the time-domain PVP measurements are filtered to generate a filtered time-domain PVP signal by removing active pumping periods. The filtered time-domain PVP signal is transformed into a frequency-domain PVP signal, which is analyzed based upon peaks indicating respiratory rate, heart rate, or harmonics thereof. A metric of patient status is then determined from the peaks or corresponding frequencies. The patient status may be related to blood volume of the patient and may be used to control pump operation.
