Combining Volumetric Capnography And Barometric Plethysmography To Measure The Lung Structure-function Relationship

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.
