摘要：
An apparatus includes a mouthpiece to communicate an airflow between a user and an airflow chamber in fluid communication with the mouthpiece an interrupter in fluid communication with the airflow chamber and adapted to initiate an occlusion event by adjusting between an open state and a closed state, such that fluid communication is at least partially prevented between the airflow chamber and ambient air during the occlusion event initiated by the interrupter a container in fluid communication with the airflow chamber a flow rate sensor in fluid communication with the airflow chamber and adapted to measure an airflow exchange between the airflow chamber and the container during the occlusion event and a controller adapted to determine an instantaneous lung volume based on the measured airflow exchange between the airflow chamber and the container.
