This specific measurement is a critical component of pulmonary function, ensuring that the alveoli remain patent and preventing the delicate lung tissues from collapsing. Significant deviations from the normal residual volume range can indicate underlying pathology.
This method relies on the principle that the inert gas will fill the entire lung capacity, including the residual space, allowing for precise calculation. During this procedure, a patient sits inside an airtight chamber and breathes against a closed shutter.
