Quizplus · Accepted Answer

The pressure-based body plethysmograph is based on Boyle's law, which states that the pressure of a gas is inversely proportional to its volume at a constant temperature. In the plethysmograph, a patient sits inside an airtight chamber and breathes normally. The pressure changes in the chamber as the patient breathes, allowing for calculations of lung volume and other measurements.
