METHOD, APPARATUS AND COMPUTER PROGRAM PRODUCT FOR ANALYSING A PULSE WAVE SIGNAL TO DETERMINE AND INDICATION OF BLOOD PRESSURE AND/OR BLOOD PRESSURE CHANGE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18276277 titled 'METHOD, APPARATUS AND COMPUTER PROGRAM PRODUCT FOR ANALYSING A PULSE WAVE SIGNAL TO DETERMINE AND INDICATION OF BLOOD PRESSURE AND/OR BLOOD PRESSURE CHANGE
Simplified Explanation
The computer-implemented method described in the abstract is for analyzing a pulse wave signal (PWS) obtained from a subject to determine an indication of the blood pressure or a change in blood pressure of the subject. The method involves analyzing the PWS to determine average cardiac cycle waveforms at different time points, calculating a difference signal representing a change in morphology between the waveforms, determining the absolute value and direction of the change in morphology, and ultimately calculating a relative blood pressure change based on these parameters.
- The method analyzes pulse wave signals to determine changes in morphology between average cardiac cycle waveforms at different time points.
- It calculates the absolute value and direction of these changes to determine a relative blood pressure change.
- The innovation provides a non-invasive way to monitor blood pressure changes in real-time.
Potential Applications
This technology could be applied in medical settings for continuous monitoring of blood pressure changes in patients. It could also be used in wearable devices for personal health monitoring.
Problems Solved
This technology solves the problem of accurately and non-invasively monitoring blood pressure changes in real-time, which can be crucial for managing various health conditions.
Benefits
The benefits of this technology include real-time monitoring of blood pressure changes, early detection of potential health issues, and improved management of cardiovascular health.
Potential Commercial Applications
Potential commercial applications of this technology include medical devices for hospitals and clinics, wearable health monitoring devices for consumers, and software solutions for analyzing pulse wave signals.
Possible Prior Art
One possible prior art in this field is the use of traditional blood pressure monitors, which are invasive and do not provide continuous real-time monitoring like the technology described in the patent application.

Original Abstract Submitted
According to an aspect, there is provided a computer-implemented method for analysing a pulse wave signal, PWS, obtained from a subject to determine an indication of the blood pressure or a change in blood pressure of the subject. The PWS comprises pulse wave measurements for a plurality of cardiac cycles of the subject during a first time period. The method comprises (i) analysing () the PWS to determine a first average cardiac cycle waveform for a first time point in the first time period and a second average cardiac cycle waveform for a second time point in the first time period; (ii) determining () a difference signal representing a change in morphology from the first average cardiac cycle waveform to the second average cardiac cycle waveform; (iii) determining () an absolute value of the change in morphology from the difference signal; (iv) determining () a direction of the change in morphology; and (v) determining () a relative blood pressure change by combining the absolute value and the direction of the change in morphology.
