Disclosed is a system and method for in-situ and instantaneous measurement of a pressure gradient by real-time localized pressure measurement with two or more pressure sensors, operating with respect to blood pressure gradient across the aortic valve, or other heart valves, and associated regurgitation of blood flow due to leakage resulting from insufficient valve closure. The system includes a multi-sensor catheter, with sensors arranged along the length of the distal segment of the catheter body, spaced apart to provide simultaneous pressure measurement on either side of the valves of the heart, in addition to one or more lumina in the core of the catheter that will provide a path for introduction of diagnostic fluids which flow out through a multitude of holes in the body of the distal segment of the catheter body.

Systems and methods for monitoring physiologic response to Valsalva maneuver (VM) are disclosed. An exemplary patient monitor may detect a natural incidence of a VM session occurred in an ambulatory setting using a heart sound (HS) signal sensed from the patient. The patient monitor may include a physiologic response analyzer to sense patient physiologic response during the detected VM session, and generate a cardiovascular or autonomic function indicator based on the sensed physiologic response to the VM. Using the physiologic response to the VM, the system may detect a target physiologic event using the sensed physiologic response to the VM.

A measurement device includes a light emitter, a light receiver, an extractor, and a processor. The light emitter illuminates an illumination target having an internal space through which a fluid flows. The light receiver receives coherent light including light scattered by the illumination target and outputs a signal corresponding to intensity of the coherent light. The extractor extracts a direct-current component from the signal output from the light receiver at a temporal change in strength of the signal. The processor calculates a calculation value for a flow state of the fluid by performing a process on the signal output from the light receiver. The process includes correction using a value of signal strength of the direct-current component and calculation of a frequency spectrum for the signal at the temporal change in the signal strength.

The present invention relates to a method for correcting pulse wave transit time associated with diastolic blood pressure and systolic blood pressure, and the correction method can perform adaptive correction of the irregular change of pulse wave transit time caused by blood transfusion and intravenous transfusion, vasoactive drugs, surgical intervention, etc. in a clinical setting. A pulse wave transit time is determined by a time difference of an ear pulse wave and a toe pulse wave in the same cardiac cycle, and a few correction variables are extracted based on the pulse wave features, then a total correction value is acquired to perform correction on the irregular change of pulse wave transit time. The corrected transit time can be used with available mathematical models for continuously measuring diastolic blood pressure and systolic blood pressure in each cardiac cycle in a clinical setting with high accuracy.
