You fill your scuba tank with pure, filtered compressed air. This is clean and safe for you to breathe under water. The air inside a tank looks like the air we take in every day. It has about 21% oxygen and most of it is nitrogen.
But before the air goes into the tank, it gets cleaned up. Dust or moisture might harm your diving gear so they need to be removed first.
Nitrox
Nitrox is a special type of breathing gas that scuba divers can use instead of regular air. It has a higher percentage of oxygen, which can be helpful for reducing the risk of decompression sickness.
Nitrox mixes typically have more than 21% oxygen, compared to the normal air we breathe. However, it’s important to remember that filling a nitrox tank with regular air is not safe for nitrox diving unless it has been properly cleaned.
When using nitrox, divers need to be aware of the maximum amount of oxygen allowed in their mix to avoid any risks. Nitrox diving can also allow divers to stay underwater longer and have shorter surface intervals between dives.
Benefits and Limitations of Nitrox Diving
Nitrox diving offers several benefits such as longer bottom times, reduced fatigue, longer dive times, and shorter surface intervals; however, it is not suitable for deep diving due to oxygen toxicity risks.
Longer bottom times
Nitrox diving can offer longer bottom times compared to diving with regular air. This is because nitrox contains a higher percentage of oxygen, which allows divers to absorb less nitrogen.
When we absorb less nitrogen, there’s a reduced risk of decompression sickness. With longer bottom times, we have more time to explore and enjoy the underwater world without having to end our dive too quickly due to nitrogen buildup in our bodies.
It’s important for divers using nitrox to be aware of the maximum partial pressure of oxygen allowed for their specific mix, as this helps ensure their safety while maximizing their dive time.
Less fatigue
Nitrox diving can help reduce fatigue during dives. This is because nitrox mixes have a higher percentage of oxygen, which allows divers to absorb less nitrogen. Nitrogen buildup in the body can cause fatigue and increase the risk of decompression sickness.
By using nitrox, divers can extend their bottom times and have longer dive durations without feeling as tired. It’s important for divers to be aware of the maximum partial pressure of oxygen (PO2) allowed for their specific nitrox mix to avoid any risks or complications.
Longer dive times
When using nitrox for diving, one of the benefits is that it can help to extend your bottom time underwater. This means you can stay down longer and explore more without needing to come up for air as often.
Nitrox has a higher percentage of oxygen compared to regular air, which allows your body to absorb less nitrogen. With less nitrogen buildup in your body, you have a reduced risk of experiencing decompression sickness or “the bends.” However, it’s important to remember that there are limits to how long you can safely stay underwater, even with nitrox.
Divers need to follow their training and be aware of the maximum partial pressure of oxygen (PO2) allowed for their specific nitrox mixture. So while nitrox may give you the advantage of longer dive times, it’s crucial to always prioritize safety and adhere to proper diving practices.
Shorter surface intervals
One of the benefits of diving with nitrox is that it allows for shorter surface intervals between dives. Surface intervals are the periods of time divers spend on the surface between consecutive dives.
With regular compressed air, divers need to wait longer to eliminate excess nitrogen from their bodies before going back underwater. However, with nitrox diving, which has a higher percentage of oxygen, less nitrogen is absorbed during each dive.
This means that divers can enjoy shorter surface intervals and spend more time exploring the underwater world instead of waiting on land. It’s important to note that proper training and understanding of nitrox diving protocols are essential to ensure safety while taking advantage of these benefits.
Importance of Using Pure, Filtered Compressed Air
Using pure, filtered compressed air is of utmost importance for scuba diving due to its safety and reliability in avoiding oxygen toxicity risks, making it the standard practice for recreational diving.
Safety and reliability
To ensure your safety while scuba diving, it’s important to use a scuba tank that is filled with either pure, filtered compressed air or nitrox. These options are considered safe and reliable for recreational diving.
Nitrox can provide benefits like longer bottom times and shorter surface intervals, but there are also limitations such as the risk of oxygen toxicity and not being suitable for deep dives.
Using pure, filtered compressed air is the standard practice for recreational diving and helps avoid potential risks. Scuba cylinders must undergo hydrostatic testing within a specified period to ensure their safety and integrity.
Avoiding oxygen toxicity risks
To avoid the risk of oxygen toxicity while scuba diving, it is important to follow certain guidelines. Oxygen toxicity can occur when we breathe in too much oxygen under high pressure for a long time.
This can cause problems like seizures and difficulty breathing. To prevent this, divers need to be aware of the maximum partial pressure of oxygen (PO2) allowed for a specific nitrox mix.
It’s also crucial to use proper equipment that delivers the correct amount of oxygen during the dive. By following these precautions and being mindful of our oxygen levels, we can ensure a safe and enjoyable diving experience without any risks of oxygen toxicity.
Standard practice for recreational diving
For recreational diving, it is standard practice to fill a scuba tank with either pure, filtered compressed air or nitrox. Pure, filtered compressed air is the most common choice and provides a safe breathing gas for divers.
It undergoes hydrostatic testing to ensure its safety and integrity. Nitrox, on the other hand, contains a higher percentage of oxygen than regular air and can offer benefits such as longer bottom times and shorter surface intervals.
However, using nitrox requires special certification and awareness of oxygen toxicity risks. By following these standard practices, divers can enjoy safer and more enjoyable underwater experiences.
Getting Nitrox Certification
To dive with nitrox, you’ll need to obtain a certification that covers the specific gas mixture. Don’t worry, it’s a straightforward process that will enhance your diving experience.
