Method and apparatus for measuring airway resistance and lung compliance

摘要

Measurement of airway resistance and / or lung compliance during non-forced exhalation is performed using an initial occlusion of exhalation, followed by removal of the occlusion or opening of a occlusion. The meter can use a single sensor to measure both pressure and flow. Pressure monitoring may detect that exhalation is not necessarily forced to signal an error or reject a pressure and flow measurement from a forced expiratory study.
