A portable, handheld device for measuring lung- and airway-specific respiratory parameters. The device defines a chamber in fluid communication with a mouthpiece. A sensor and/or a flow sensor monitor pressure and/or airflow within the device. A respiratory gas source, e.g., an internal pump, or an external compressor, is also in fluid communication with the chamber and a mouthpiece. The device operates in an active phase and a passive phase. In the active phase, a subject forcibly exhales into the device and the sensors collect spirometric data. In the passive phase, the pump is activated to pump air from the device and inflate the subject's lungs to a specific capacity. The sensors monitor pressure and/or flow as the air is introduced into the subject's respiratory system. The data collected by the sensor is used to determine lung and airway specific parameters, including but not limited to, airway conductance, airway resistance, airway compliance and total lung capacity.
