What is the best type of breathing gas for scuba diving?

Introduction

Scuba diving is an amazing sport that allows you to explore the underwater world and witness the beauty of marine life. However, it is important to use the right breathing gas to ensure a safe and enjoyable diving experience. There are different types of breathing gases available for scuba diving, and each has its own advantages and disadvantages. In this article, we will discuss the best type of breathing gas for scuba diving.

Types of Breathing Gas

The most common types of breathing gas used for scuba diving are air, nitrox, and trimix.

Air

Air is the most commonly used breathing gas for scuba diving. It is composed of 21% oxygen and 79% nitrogen. The advantages of using air are that it is readily available, cheap, and easy to use. However, there are also some disadvantages of using air. The nitrogen in air can cause nitrogen narcosis at deeper depths, which can impair your judgment and coordination.

Nitrox

Nitrox is a breathing gas that has a higher percentage of oxygen than air. It typically contains 32% to 36% oxygen, which reduces the amount of nitrogen in the gas. The advantages of using nitrox are that it reduces the risk of nitrogen narcosis, allows for longer bottom times, and reduces the risk of decompression sickness. However, there are also some disadvantages of using nitrox. It is more expensive than air, requires special training and equipment, and can be dangerous if not used correctly.

Trimix

Trimix is a breathing gas that contains a mixture of oxygen, nitrogen, and helium. It is typically used for deep diving beyond 130 feet. The advantages of using trimix are that it reduces the risk of nitrogen narcosis and decompression sickness, allows for longer bottom times, and reduces the risk of oxygen toxicity. However, there are also some disadvantages of using trimix. It is expensive, requires special training and equipment, and can be dangerous if not used correctly.

Conclusion

In conclusion, the best type of breathing gas for scuba diving depends on your diving goals and experience level. For recreational diving, air or nitrox is sufficient. For technical diving beyond 130 feet, trimix is recommended. It is important to receive proper training and use the correct equipment when using any type of breathing gas for scuba diving.
