摘要

Method and the device which detect the tubular condition of the one lung of the human acoustic are offered. According to one execution example, method of this invention includes the step which calculates the self recursive moving average (ARMA) with self regression function of the electric information which is received from the acoustic sensor which is arranged in the various places of the human body. The arrangement place of the acoustic sensor is the back or the chest of the human body. Method and the device of this invention do not have an influence on the random background noise before kiyaseru of the operation interior. With the method and the device of this invention, relative rate of occurrence of erroneous detection, false positive and the false negative is corrected. According to one execution example, maximum of 9% it identifies, is false positive, maximum of 2% is the false negative.
