breathing gas

Breathing gas is the mixture of gases we inhale to sustain life or perform specific activities like diving. The most common mixing consists mainly of oxygen and nitrogen, but specialized blends can include helium or other gases to improve safety and performance at different depths or conditions. These gases are carefully prepared to prevent issues like oxygen toxicity or nitrogen narcosis and are delivered through equipment like masks or scuba tanks. Understanding and controlling the composition of breathing gases is essential for safety and efficiency in various applications, especially in activities requiring controlled or enhanced respiration.
