US 2026/0262950 A1 · Blood Pressure Monitoring Method, Wearable Device, and Storage Medium

Abstract

A wearable device obtains motion data collected by a motion sensor and a first PPG signal collected by a PPG module, and when one or both of the motion data and the first PPG signal meet a first condition, the wearable device determines whether a user is in a sleep state, and when determining that the user is in a first sleep event, the wearable device obtains a first blood pressure value. The first sleep event includes any one or more of an OSA event, a REM event, an NREM sleep event, and an elevated central sympathetic nerve activity event. When a specific sleep event is detected, blood pressure starts to be measured, and when no specific sleep event is detected, the blood pressure stops being measured.

Dependent claims

A method implemented by a wearable device and comprising:

receiving a first user operation, wherein the first user operation comprises instructions to measure a user blood pressure when detecting a sleep event of a user, wherein the sleep event comprises one or more of an obstructive sleep apnea (OSA) event, a rapid eye movement (REM) event, a non-REM (NREM) sleep event, or an elevated central sympathetic nerve activity event;
obtaining motion data from a motion sensor;
obtaining a first photoplethysmography (PPG) signal from a PPG obtainer;
determining, based on one or more of the motion data or the PPG signal meeting a condition, a sleep state of the user;
and
measuring the user blood pressure when detecting that the sleep state comprises the sleep event to obtain a first blood pressure value of the user.

3 more elements

A wearable device, comprising:

a motion sensor configured to obtain motion data;
a photoplethysmography (PPG) obtainer configured to obtain a first PPG signal;
one or more processors;
and
a non-transitory computer-readable storage medium coupled to the one or more processors and configured to store programming instructions, wherein the programming instructions, when executed by the one or more processors, cause the wearable device to:
receive a first user operation, wherein the first user operation comprises instructions to measure user blood pressure when detecting a sleep event of a user, wherein the sleep event comprises one or more of a non-REM (NREM) sleep event, or an elevated central sympathetic nerve activity event;
obtain the motion data from the motion sensor;
obtain the first PPG signal from the PPG obtainer;
determine, based on one or more of the motion data or the first PPG signal meeting a condition, a sleep state of the user;
and
measure the user blood pressure when detecting that the sleep state comprises the sleep event to obtain a first blood pressure value of the user.
