FRC is the sum of expiratory reserve volume (ERV) and residual volume (RV) and measures approximately 3000 mL in a 70 kg, ... helium dilution or body plethysmography. Positioning plays a significant role in altering FRC. It is highest when in an upright ... It cannot be estimated through spirometry, since it includes the residual volume. In order to measure RV precisely, one would ... Functional residual capacity (FRC) is the volume of air present in the lungs at the end of passive expiration. At FRC, the ...
