Microwave non-invasive sensing of respiratory tidal volume.
This paper describes the use of Doppler radar to measure respiration rate and air volume. The respiratory volume is measured indirectly via chest wall position. Calibration of displacement to airflow prior to subject measurements and accurate chest wall position information enable mean differences of less than 10 ml; with standard deviation of the difference of 20 ml between radar and reference measurements.
