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.

Description

[0001] related application [0002] This application claims U.S. Provisional Application No. 62 / 000,078, filed May 19, 2014, entitled "Method of Calibrating a Non-Interfering Continuous Blood Pressure Measurement Device," and filed October 30, 2014, entitled U.S. Provisional Application No. 62 / 072,568 for "Continuous Calibration of Non-Interfering Blood Pressure Device," and "A Method of Estimating the Transmural Pressure in an Artery of a Subject with a Non-Interfering Priority to U.S. Provisional Application No. 62 / 072,601 for "Continuous Blood Pressure Measuring Device", the entire contents of each of the above applications are hereby incorporated herein by reference. Background technique [0003] Devices for making measurements of cardiovascular properties suffer from the problem that the measurements themselves strongly interfere with the state of the subject, leading to erroneous results. This is especially the case with current cuff-based methods that may confer signif...
