What is a Gas Fraction?
In the context of scuba diving, a gas fraction refers to the proportion of each gas component within a breathing gas mixture. Understanding gas fractions is crucial for divers to ensure safe and efficient breathing under water. The significance of gas fractions cannot be overstated, as they directly influence dive planning, physiological effects on the body, and overall safety. By grasping the fundamentals of gas fractions, divers can make informed decisions that enhance their underwater experience while minimizing risks.
