A whole-body plethysmograph is a diagnostic system that measures lung function by recording airway resistance and thoracic gas volume while a patient sits inside an airtight chamber. Clinicians use it to evaluate pulmonary mechanics, diagnose obstructive or restrictive lung diseases, and monitor treatment effects.
These devices are classified as medical equipment and must meet applicable safety and performance standards, with regulatory classification varying by jurisdiction. They are typically supplied as complete systems that include the chamber, pressure transducers, and recording software.
