What is the average lung capacity of an adult diver?

The average lung capacity of an adult diver is approximately 6 liters. This measure refers to the total volume of air that the lungs can hold and is generally consistent among adults. Lung capacity can vary depending on factors such as age, gender, body size, and fitness level.

Understanding this average is essential for divers, as it relates to how gas is exchanged in the lungs during diving. The ability to efficiently use the available lung capacity can affect buoyancy control, respiratory performance, and overall diving physiology. Knowing that the typical lung capacity is around 6 liters helps divers appropriately plan for air consumption and manage risks associated with underwater breathing, particularly in terms of equalization and avoiding barotrauma.

The other figures represent lung capacities that can exceed normal ranges, which are not as commonly observed and may not be representative of the typical adult population.
