WebJan 1, 2012 · Increased lung volumes, particularly residual volume (RV), are commonly observed in airway obstruction. TLC may be normal, but is frequently increased in the late stages of COPD. Hyperinflation and air-trapping are terms commonly used to reflect these changes, but are not well standardized. WebJul 5, 2024 · There are two equations needed to calculate the volume that enters the lungs and the volume that reaches the alveoli. The volume that enters the lung per minute is known as minute ventilation (VE). The equation states VE equals tidal volume (VT) multiplied by respiratory rate (RR).

WebOther lung volumes including total lung capacity (TLC) and residual volume (RV) must be measured via plethysmography, which is typically performed in a pulmonary function laboratory. TLC is increased in COPD, particularly in the presence of emphysema where there is significant loss of elastic recoil, resulting in lung hyperinflation. gunnar johansson solna
