1. The helium dilution technique measures functional residual capacity (FRC) by using a closed circuit containing a known concentration of helium gas that the patient breathes. As helium mixes uniformly between the lungs and spirometer, FRC can be calculated using gas laws and concentrations. 2. Physiological dead space includes anatomical dead space plus alveolar dead space from poorly perfused alveoli. The Bohr equation calculates physiological dead space from end-tidal and arterial CO2 measurements bas
