Comparison table with previous studies.
| Reference | Main parameters | Result (final or mean) |
| In the paper [25] | Oxygen saturation (SpO2) | () % The oxygen saturation for sleep apnea patients is in this range | In the paper [6] | Heart rate | () bpm The study detected sleep apnea in this range of heart rate. | In the paper [26] | Polysomonography | 91.8% to 96.5% accuracy on adaptive apnea index | In the paper [27] | Snoring sound intensity | 45 dB to 58 dB and mean value is approximately 52 dB | In the paper [11] | 3D camera | A novel approach has been proposed to measure respiratory movement using a 3D camera to detect apnea. | Our system | SpO2, heart rate, ECG, skin response, snoring sound intensity | SpO2: 94.55 to 97.81 BPM: 74.47 to 91.39 GSR: 128.95 to 275.45 Sound: 35 dB to 60 dB ECG: generalized |
