An ANN-Based Detection of Obstructive Sleep Apnea from Simultaneous ECG and SpO2 Recordings

Sleep apnea syndrome detection and classification of severity level from ECG and SpO2 signals

“…However, this work focuses only on detecting sleep apnea events and achieved low accuracy compared to our result. Another study has achieved an accuracy of 98.1% by using ECG and SpO 2 for detecting sleep apnea which is less compared with our result and severity classification also not included compared with our result (19). Sleep apnea severity classification using the ECG signal alone has been proposed based on a deep learning approach (26).…”

“…However, the system has low accuracy and severity detection was not included in their system. A system that used an artificial neural network-based detection of OSA from ECG and SpO 2 in combination was also developed and tested using 12 features from ECG signal and 2 features from and an accuracy of 98.3%, a specificity of 100% and a sensitivity of 96.6% was reported (19). Even though the accuracy achieved was good severity classification has not been considered.…”

“…It allows users to load ECG and SpO 2 data, pre-process the signals, classify the signal and identify the severity level if it is apnea positive. (10)(11)(12)15,16,24), and in a few cases also based on a combination of ECG and SpO 2 (19,25). However, in most literature, either the data used for training and testing or the accuracy claimed is less which compromises the reliability of diagnosis.…”

Fusion of Whole Night Features and Desaturation Segments Combined with Feature Extraction for Event-Level Screening of Sleep-Disordered Breathing

“…Many studies have addressed these issues by using signals from audio recordings, 5 plethysmography, 6 respiratory movements, 7 , 8 oximetry, 9–16 electrocardiogram (ECG), 17 or a combination of such methods. 18 , 19 The SpO 2 signal can be easily collected, and a large number of wearable pulse oximetry devices are available in the market at a low cost. 20–22 The SpO 2 signal represents the oxyhaemoglobin concentration in blood.…”
