This method can help answer key questions in pulmonary physiology, particularly about how the structure-function relationship in the lung contributes to disease pathology. The main advantage of this technique is that it allows measures to be made

Here, we describe two measures of pulmonary function – barometric plethysmography, which allows the measurement of lung volume, and volumetric capnography, a tool to measure the anatomic dead space and airways uniformity. These techniques may be used independently or combined to assess airways function at different lung volumes.
