Residual Volume (RV) Volume of air remaining in the lungs even after aforcible expiration. Atemvolumen, Expiratory reserve volume is an important measurement of lung function testing that, when combined with results from other PFTs, is primarily used to diagnose and distinguish between lung diseases such as chronic obstructive pulmonary disease (COPD), asthma, and pulmonary fibrosis.2 Because imaging of the lungs, such as X-rays or computerized tomography (CT) scans, often cannot make these distinctions, PF… IC = IRV+TV. Obtain inspiratory reserve volume (IRV), the maximum possible amount of air inhaled beyond the inhalation of a normal breath, on a dry spirometer by finding the sum of the tidal volume and expiratory reserve volume and subtracting this value from the vital capacity (IRV = VC - (TV + ERV)). Tidal volume-The amount of air breathed in and out in normal quiet breathing.It is about 500 ml. P=2T/R (P) Pressure in sphere, (T) Surface Tension of liquid, (R) radius of sphere.
