Total lung capacity

Tidal breathing is normal, resting breathing; A stronger and larger lung capacity allows more air to be inhaled into the lungs. The average maximum capacity is around 6 liters of air, but when you exhale approximately 1. It is perhaps rather generally assumed that reasonably adequate information is already avail-able concerning these tests, which have been in use for some In contrast, volumes and capacities, such as residual volume (RV) and functional residual capacity (FRC) increase, while vital capacity (VC) and inspiratory capacity (IC) fall as a result of airway closure, progressive hardening of lung tissue, and loss of elastic recoil pressure.

Inspiratory Reserve Volume (IRV): additional air that you can force into your lungs after you breathe in the tidal volume. 5. The strength of your inspiratory muscles and the physical properties of the lungs and chest wall determine your total lung capacity. There are different volumes of air that are normal for different stages of the respiratory cycle, so a normal lung capacity is constantly changing. At total relaxation of the muscles of inspiration and expiration, the lung is distended to a volume—called the functional residual capacity—of about 40 percent of its maximum volume at the end of full inspiration. by Greg Crowther Context This is a musical rendition of the respiration equation RV + ERV + V T + IRV = TLC.
