BLOOD PRESSURE ESTIMATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18271943 titled 'BLOOD PRESSURE ESTIMATION

Simplified Explanation

The patent application describes a computer-implemented method for estimating blood pressure by analyzing blood volume and respiration signals of a subject.

  • The method involves processing blood volume and respiration signals to identify cardiac cycles and respiration cycles of the subject.
  • A subset of blood volume signal segments is selected based on the corresponding respiration cycle phase.
  • Blood pressure is estimated using morphology features of the selected blood volume signal segments.

Key Features and Innovation

  • Utilizes blood volume and respiration signals to estimate blood pressure.
  • Selects specific blood volume signal segments based on respiration cycle phases.
  • Analyzes morphology features of the selected segments for accurate blood pressure estimation.

Original Abstract Submitted

According to an aspect, there is provided a computer-implemented method of estimating blood pressure of a subject. The method comprises (i) processing () a first blood volume signal to identify a plurality of blood volume signal segments each corresponding to a respective cardiac cycle of the subject, wherein the first blood volume signal comprises measurements of blood volume or changes in blood volume in a body part of the subject in a first time period; (ii) processing () a first respiration signal to identify a plurality of respiration cycles of the subject in the first time period, wherein the first respiration signal represents respiratory activity of the subject during the first time period, and wherein each respiration cycle comprises a plurality of respiration cycle phases; (iii) selecting () a subset of the plurality of blood volume signal segments, wherein the blood volume signal segments selected for the subset are blood volume signal segments corresponding in time to a same respiration cycle phase in the plurality of respiration cycles; and (iv) estimating () blood pressure of the subject based on morphology features of the blood volume signal segments in the subset.
