Respiratory Measurement of Volume Change Using Accelerometer, Thermographic Camera Electrical Impedance Tomography and Motion Correlation Analysis Using Mattress Sensor in Healthy Individuals

Study Overview
=================
Brief Summary
-----------------
Tidal volume can be the most important technical indicator for ventilation. Measuring the volume of breathing can be used as an indicator of how effective a patient's gas exchange is, and as a predictive indicator of the statue of respiratory disease indirectly. These Tidal volumes can be measured using spirometry and pneumotachograph, and the breathing volume and the rate of airflow can directly or indirectly evaluate the lung function of the patient. However, spirometry has limitations that patients who are difficult to measure, and that it is difficult to measure in bed. In this work, the movement of the thorax due to breathing is measured in a non-invasive manner (accelerometer, thermographic camera) and the accuracy is compared through changes in thoracic impedance obtained through Pulmovista 500. Furthermore, we would like to correlate the motion of the measured object through a mattress sensor.
