WebBackground: Functional Residual Capacity (FRC) iis the point we breathe at and is the balance point between the chest wall and lung compliance. Hyperinflation is the ratio of FRC to total lung capacity (TLC), whilst gas trapping is the residual volume (RV) to TLC ratio.

WebRV is the difference between TLC and VC, the maximum amount of air one can breathe out from TLC. Forced vital capacity (FVC) is the VC obtained during maximum expiratory effort. Normally, FVC and VC in the same healthy person are nearly identical, but in patients with obstructive airway disease, airway closure worsens with effort and FVC may ... WebThe ratio of FEV1 to FVC is an indication of an airways diameter. The higher the value, the faster air can flow through the airway, therefore, the lower the resistance and the wider the airway
WebFeb 1, 2015 · RV = FRC – ERV and TLC = RV + SVC or TLC = FRC + IC and RV = TLC – SVC. IC and ERV are not measured from an FVC maneuver but only from an SVC maneuver. If the SVC is suboptimal, there is no way to know whether the IC or the ERV is correct or whether they are suboptimal as well.
