Chronic sleep apnea disorder is likely to bring the declining the sleep quality, getting out of sleep rhythm, and decrease of the blood oxygen levels. Particularly, the patient with chronic heart failure, it worsens imbalance of oxygen transfusion/consumption balance, modulation of neurohumoral factor activity and increase heart load. Consequently, they become a cause of worsening heart failure, and have a significant impact on the prognosis. Therefore, we need to find breathing disorder at early stage, lead to treatment. Currently, there are the monitoring system using PSG, Respiration Stability Index(RSI). It is said RSI can monitor the stability of breathing cycle, sleep quality by analyzing frequency. Currently it has been developing wearable or non-contact monitor.

In this study, we detected the motion of chest from images shot by non-contact with Depth camera. Furthermore we analyzed comparison with the result of the evaluation of respiratory condition acquired by respiratory sensor.
