Abstract: Various embodiments identify valid arterial pulses of a subject. The method may include accessing one or more measured pulses from one or more arterial measurement sensors. The processor may identify one or more valid pulses from the one or more measured pulses based on a comparison of one or more pulse characteristics of the one or more measured pulses to one or more reference pulses. The one or more pulse characteristics are determined based on the one or more measured pulses and a wavelet transform. The wavelet transform is determined based on the one or more reference pulses.

Abstract: A system for calculating blood pressure may include a sensor system and a control system. The control system may be capable of controlling one or more sensors of the sensor system to take at least two measurements, the at least two measurements including at least one measurement taken at each of two or more different measurement elevations of a subject's limb. In some examples, the control system may be capable of determining a blood flow difference based on the at least two measurements, of determining a hydrostatic pressure difference based on the two or more different elevations of the at least two measurements and of estimating a blood pressure based on one or more values of blood flow, the hydrostatic pressure difference and the blood flow difference.

Abstract: Systems, methods, and devices of the various embodiments enable continuous non-invasive monitoring of blood pressure with a minimum of interference. The various embodiments may provide a method for adaptation for the calibration for continuous measurements of blood pressure, wherein the measured quantity may be related to an arterial lumen or arterial cross sectional area comprising calibrating the conversion for incremental variations of arterial properties and absolute value adaptation by exploitation of the exponential decay during the diastole. In various embodiments, continuous calibration of a non-interfering blood pressure measurement device may be initiated based on a change in mean arterial pressure being greater than a threshold value, such as a pressure value associated with an actual measured distension of a patient's artery.

Abstract: Various embodiments include methods and devices for measuring blood pressure. Various embodiments may include receiving, from one or more arterial measurement sensors, a pulse waveform representing arterial pressure as a function of time for each pulse of a series of blood pressure pulses. The series of blood pressure pulses may be correlated to arterial distension at a measurement location of the arterial measurement sensors on a subject's body. One or more elevations of the measurement location may be received from one or more elevation sensors. At least one pulse in the series of pulses may be identified that represents a transitional pulse based on one or more characteristics of the at least one pulse. A diastolic blood pressure may be determined based on the at least one identified transitional pulse and elevation measurements that correspond to the one identified pulse.

Abstract: An optical sensor and a method of using the optical sensor in an optical measuring device that measures cardiovascular properties and compensates for movement artifacts by directing a sheet of light towards an artery. The optical sensor may include one or more light sources, one or more transmit light guides coupled to the one or more light sources and configured to direct light from the one or more light sources as a sheet of light towards an artery, such that the cross-sectional profile of the sheet of light may have a length transverse to a longitudinal direction of the artery that is longer than the diameter of the artery. The optical sensor may include one or more light detectors configured to receive backscattered light and generate an output based on the received backscattered light that is a reflection of the sheet of light from the artery and surrounding tissues.
