In order to measure the respiratory impedance clinically with oscillation method, calibration is sometimes complex because of frequency characteristics of the calibratin coefficient, nonlineality and presence of the impedance of the measurement system itself. This study shows clinical application of the calibration technique using three resistance tubes for the oscillation method with random noise input. This technique includes the concepts of impedance and phase angle of the measurement system itself, and of frequency characteristics of the calibration coefficient calculated by regression line. We have reported the decrease of respiratory impedance, during inhalation anesthetics, measured by forced oscillation method with this calibration technique. It is concluded that this calibration technique will give easy measurement of respiratory impedance with oscillation method.
