Abstract

It is said that sleep apnea syndrome is one of the main causes of airplane, train and car accidents. We have developed a non-contact breathing measurement system which diagnoses not only sleep apnea syndrome but also other sleep disorders. This system calculates the amount of the volume change and makes the movement of the outside of the body by the breath motion visible. If the patient is breathing abnormally, we are able to recognize the appearance of abnormality at a glance and know the amount of the volume change in that location. To verify the amount of the volume change, we compare the amount of ventilation measured with a spirometer to the amount of volume change measured with this system. As a result, there is a high correlation in the amount of the volume change and the amount of ventilation in any sleeping position
