The present invention relates to a system and method for the enhanced detection and quantification of respiratory events, such as apneas and hypopneas, particularly useful in diagnosing and managing sleep-disordered breathing conditions. This system integrates sophisticated machine learning algorithms, specifically one-dimensional convolutional neural networks (1D CNNs), with advanced signal processing techniques to analyze physiological signals. It focuses on the detecting respiratory event with a localized portion of the input segment, a novel approach that increases specificity in event detection. The system segments physiological signals into overlapping segments, each analyzed by the machine learning model to generate a prediction score. A unique aspect of this invention is the application of a dual-threshold mechanism: a ‘Model threshold’ for initial event identification and a ‘Vote threshold’ for confirming events through an aggregate voting process of overlapping segment predictions. This innovative approach ensures high accuracy and reliability in event detection and counting.

This invention provides a bed-mounted sleep breathing state monitoring system and method. It collects bed-mounted pressure signals generated during the user's sleep process using an under-bed pressure sensor module. Based on these signals, it determines the start and end times of candidate sleep breathing abnormalities.

This method accurately captures the complete temporal features of sleep breathing abnormalities without relying on fixed time window segmentation, effectively avoiding issues such as event truncation and feature aliasing. It achieves adaptive localization and automated detection of sleep breathing abnormalities, significantly improving the accuracy and completeness of sleep breathing abnormality event identification and reducing the risk of missed or false detections.
