AI Technical Summary

Problems solved by technology

However, for elderly subjects, their arteries are stiffer due to age and so the velocity of the pulse wave is high, causing the reflected wave to return faster, thus causing the separation between the systolic and diastolic peaks to decrease
The dicrotic notch and diastolic peak of the pulse wave thus become visually indistinguishable from the sum of the waves

Embodiment Construction

[0042] figure 1 is a schematic block diagram of an apparatus 100 for measuring the blood pressure of a (human) subject 102 according to the first embodiment. In particular, measuring blood pressure herein is instructing the mean arterial pressure of subject 102 . The device 100 comprises an optical measurement device 110 comprising a signal sensing module 112 for obtaining biological signals from the subject 102 . The optical measurement device 110 further comprises a data processing module 114 (eg a processor) arranged to receive and process biological signals from the signal sensing module 112, and a wireless / wired transmission module 116 for transmitting data processed from the biological signals. It will be appreciated that the optical measurement device 110 is preferably arranged for portability, eg, in a palm-sized form factor.

[0043] The transmission module 116 of the optical measurement device 110 is arranged to communicate wirelessly / non-wirelessly with a telecom...

Abstract

A method of deriving mean arterial pressure of a subject is disclosed. The method includes: (i) receiving (202) from a subject data related to at least one heart cycle of a biosignal; (ii) normalizing the received data related to at least one heart cycle; (iii) calculating (206) the area enclosed by the normalized received data to obtain a normalized area; (iv) calculate (208) the subject's heart rate from at least one cardiac cycle; and (v) calculate (208) the subject's heart rate from the normalized Area and heart rate are used to derive (210) mean arterial pressure. A related device is also disclosed.

Description

technical field [0001] The present invention relates to a method and apparatus for deriving the mean arterial pressure of a subject. Background technique [0002] Arterial blood pressure measurements provide valuable information about a patient's cardiovascular system. A normal cardiovascular system is characterized by adequate blood flow to all parts of the patient's body without prolonged stress on the physical capabilities of the various organs through which blood flows. In abnormal cardiovascular systems, blood pressure can be too high or too low, with each abnormality having attendant consequences for various body parts. The resulting prolonged stress can lead to heart disease, liver disease and kidney disease and / or other complications. The importance of arterial blood pressure has thus stimulated the development of many methods for determining arterial blood pressure. [0003] Currently, auscultation and oscillometric techniques are the most widely used techniques ...
