Apparatus and Methods for Screening, Diagnosis and Monitoring of Respiratory Disorders
Summary
The USPTO granted ResMed Pty Ltd Patent US12594025B2 covering a medical device that uses ECG sensors, accelerometers, and photoplethysmographs (PPG) to detect sleep-disordered breathing (SDB) events. The patent includes 20 claims and covers methods for screening, diagnosis, and monitoring of respiratory disorders using multi-sensor signal analysis.
What changed
The USPTO issued Patent US12594025B2 to ResMed Pty Ltd, covering a device and methods for detecting sleep-disordered breathing events using combined ECG, accelerometer, and PPG sensor data processed by a configured processor. The patent claims priority to Application No. 18637942 filed April 17, 2024, and includes 20 claims covering the multi-sensor detection methodology and device configurations.
Manufacturers developing similar multi-sensor diagnostic devices for respiratory or sleep disorders should evaluate whether their technology falls within the scope of these claims. ResMed now holds exclusive rights to this specific multi-sensor SDB detection approach in the US market, potentially affecting product development strategies for competing respiratory screening technologies.
What to do next
- Monitor for patent infringement if developing similar respiratory screening technology
- Review licensing options from ResMed if planning to commercialize related diagnostic devices
- Consider design-around strategies for competing products in sleep-disordered breathing detection

Abstract
A device that may include, or communicate with, sensors such as an electrocardiogram (ECG) sensor, an accelerometer, and/or a photoplethysmograph (PPG) detects sleep-disordered breathing (SDB) events of a patient based on signals from the sensors. The device may have a processor configured to make the detection(s). In an example, the processor may access a memory with processor control instructions. The instructions may be adapted to configure the processor to carry out the detection methodology. The method may include analysing an ECG data of the patient from a signal generated by the ECG sensor, pulse oximetry data of the patient from a signal generated by the PPG, and a three-dimensional (3D) accelerometry data of the patient from a signal generated by the accelerometer to detect the SDB events. The device and methods may be used for screening, diagnosis and monitoring of respiratory disorders.
