The 9 components of a Pulmonary Function Test (PFT) typically include: forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC ratio, peak expiratory flow (PEF), forced expiratory flow (FEF), total lung capacity (TLC), residual volume (RV), functional residual capacity (FRC), and diffusing capacity of the lungs for carbon monoxide (DLCO).
Functional Residual Capacity (FRC) = Expiratory Reserve Volume (ERV) + Residual Volume (RV)
The Inspiratory reserve volume (IRV) is calculated by subtracting the tidal volume and expiratory reserve volume from the total lung capacity. In this case, the total lung capacity is the sum of the active capacity and the expiratory reserve volume, which equals 5660ml. Therefore, the IRV would be 5660ml - 500ml - 1300ml = 3860ml.
It's the inspiratory reserve volume plus the tidal volume plus the expiratory reserve volume

Vital capacity is the amount of air you can breathe out after a maximum inhale. When it comes to determining vital capacity it’s basically calculated by the inspiratory reserve volume in addition to the expiratory reserve volume.

TV means tidal volume, ERV means expiratory reserve volume, and VC means vital capacity.
Reducing the radius of the airways will affect the capacity of the lungs to exhale the maximum amount of air

Vital Capacity (VC) is the maximum amount of air that can be exhaled after a maximum inhalation. But it differs from one person to another. For a normal sized male that would be 4600 ml.
