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.

=== Unanswered Questions ===

== How does this technology compare to traditional blood pressure monitoring methods? ==
The article does not provide a direct comparison between this technology and traditional blood pressure monitoring methods in terms of accuracy, reliability, and ease of use.

== What are the limitations of this technology in terms of detecting certain types of blood pressure changes? ==
The article does not address any potential limitations of this technology in detecting specific types of blood pressure changes, such as sudden spikes or drops.


==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.
