ABSTRACT:
A method for determining airflow in a portion of a respiratory tract comprising determining a total acoustic energy in a region of a body surface overlying the portion of the respiratory tract. The airflow may be integrated over a time interval in order to determine an air volume that has flowed in the portion of the respiratory tract during the time interval. A graph of the flow rate as a function of the volume may be displayed and analyzed as in spirometry. The invention also provides a system for carrying out the method.
