Functional Residual Capacity (FRC) = Expiratory Reserve Volume (ERV) + Residual Volume (RV)
residual (reserve) volume
Total lung volume equals Vital Capacity + Residual Volume.
The increased residual volume and decreased vital capacity indicates difficulty in breathing. There are many conditions that can make the breathing capacity to reduce.
Residual volume is the amount of air left in the lungs after a maximal exhalation
No, vital capacity is the maximum volume a person can exhale after taking the deepest breath that they can
Residual volume
functional residual capacity 2300 Inspiratory capacity 3500 Vital capacity 4600 Total lung capacity 5800
The air that can not be exhaled is called residual volume.TV = the amount of air displaced during normal breathing.IRV = The amount of air that can be taken in forcibly beyond tidal volumeErv= The amount of that can be expelled forcibly.Vital capacity = the total amount of exchangeable air.Total Lung capacity = TV + IRV + ERV + RESIDUAL VOLUME
What happens is the vital capacity of the lungs greatly increases over time while residual volume decreases. Essentially the body is becoming more conditioned and the entire cardiovascular system improves, therefore it does not need the extra residual volume. However, if someone were to not exercise at all the opposite would occur. Source: Fitness For Life class I was in during winter quarter of 2011.
residual volume
the volume capacity of a normal compact disk lise in between 650mb to 900mb
