Method for measuring the acoustic impedance of the respiratory system and method for monitoring the progress of treatment for respiratory diseases or disorders

摘要

This invention offers the method of measuring the acoustic impedance of breathing apparatus type. This method, includes thing, the fact that the sound wave is directed inside breathing apparatus system, and receives the sound wave from breathing apparatus system the fact that the frequency range of the sound wave is selected. In addition as for this method, also calculating the plural capacities of breathing apparatus type or the acoustic impedance of the capacity range includes. The acoustic impedance where each capacity or capacity inside each capacity range is larger than RV or FRC and at the same time is smaller than TLC, is required with that, is specific to the respective capacity or the capacity range. Furthermore, this method includes the fact that to quality it converts breathing apparatus system by analyzing the dependancy for the capacity of thing, and the acoustic impedance which seek the dependancy for the capacity of acoustic impedance of breathing apparatus type or capacity range or capacity range.
