How deep can you dive on 32% nitrox?

How deep can you dive on 32% nitrox?

121 feet
However, when diving on nitrox, the potential for oxygen toxicity lurks well within the depth range of recreational diving: the maximum depth on 32 percent nitrox is 121 feet; on 36 percent nitrox, it’s just over 100 feet. Many divers regularly cruise at these depths and even deeper without giving it a second thought.

How deep can you go on 30 nitrox?

The gas mix was developed based on two criteria: a maximum operating depth of 130 feet and a maximum oxygen partial pressure of 1.6 atmospheres absolute (ATA).

How deep can you dive on 40% nitrox?

With nitrox, the depth limit is within recreational diving depths, and the more oxygen, the shallower the limit – the limit is the depth at which the PPO2 would be 1.4 ata. Long term exposure to elevated oxygen can cause a different type of oxygen exposure as well.

What is the most common nitrox blend?

A: Nitrox (oxygen enriched air) is any mixture of oxygen and nitrogen. The most common nitrox mixtures used in recreational diving are nitrox 32 (32% oxygen and 68% nitrogen) and nitrox 36 (36% oxygen and 64% nitrogen).

How do you read an air dive table?

The letters range in sequence from A to L. The letter A represents a small amount of nitrogen and the amount of nitrogen increases as the letters progress towards L. When you dive, a Letter Group from the tables designates the amount of nitrogen you have absorbed during the dive.

What is the mod for 32 nitrox?

Nitrox MOD Table

in feet (saltwater) in meters (saltwater)
30% 121 43.3
31% 116 41.6
32% 111 40.0
33% 107 38.5

How long can you stay underwater nitrox?

Therefore, even diving with Nitrox, this diver can only dive for maximum 30 minutes regardless of how much time before he reaches the no decompression limit. As a result, diving with nitrox does not offer a longer dive time for this diver. Diving with Nitrox reduces the risk of decompression sickness.

How deep can you go on 28 nitrox?

Nitrox maximum depths

Fraction of oxygen (FO2) Maximum depth for partial pressure of oxygen (PPO2) of 1.4 Maximum depth for partial pressure of oxygen (PPO2) of 1.6
27% 42 49
28% 40 47
29% 38 45
30% 37 43

What depth should you use nitrox?

Can you put regular air in a nitrox tank?

Yes. You should do everything possible to ensure they stay O2 clean, and only ever fill them using Oxygen compatible air. Standard scuba air, although very clean and dry, may still contain trace amounts of hydrocarbons and other contaminants.

How deep can you dive without Nitrox?

If nitrogen causes narcosis and you’re breathing less of it, you should have less narcosis. The trouble is, the depth range where you start worrying about narcosis (100 to 130 feet) is also where you have to stop using nitrox because of the risk of oxygen toxicity.

How deep can I dive without decompression?

130 feet
How deep can you dive without decompression? Practically speaking, you can make no stop dives to 130 feet. While you can, in theory, go deeper than that and stay within no stop limits, the no stop times are so short that “well within” limits is essentially impossible.

How deep can you dive with nitrox 40?

This mix allowed a maximum operating depth of 130 feet (ca. 40 m) and a maximum oxygen partial pressure of 1.6 atmospheres absolute (ATA), also noted as PO2 of 1.6.

How do you calculate nitrox?

If we want to dive with a maximum oxygen partial pressure of 1.4 bar the process of finding the “right” blend of nitrox simply requires us to divide 1.4 by 3.6, which equals 38.8, and that is the blend of nitrox (the percentage of oxygen) that would work for our dive!

What is the MOD for 32 nitrox?

When using enriched air with up to 40% oxygen choose all that apply?

When using enriched air with up to 40% oxygen (check all that apply): Generally, you may use standard scuba equipment(except cylinder). Use of oxygen compatible lubricants is generally recommended. Follow all manufacturer recommendations regarding using their equipment with enriched air.

What percent oxygen is nitrox?

approximately 21 percent oxygen
Air, of course, is basically a nitrox mix of approximately 21 percent oxygen and 79 percent nitrogen. For divers, enriched air Nitrox is any gas blend with more than 21 percent oxygen. Generally for recreational divers this is a blend of either 32 percent or 36 percent oxygen, sometimes abbreviated EAN32 or EAN36.

How much longer can you stay down with nitrox?

At 60 feet, the diver’s maximum time would be 55 minutes. But, nitrox changes these numbers. Because you’re breathing less nitrogen, less dissolves into your body, all else being equal, allowing a longer no-decompression limit.

Do you use less air with nitrox?

Although you are breathing more oxygen and less nitrogen, the amount you breathe and the rate you consume the contents of your tank is not affected by the mixture. In fact, you’re more likely to use your tank’s contents more quickly on Nitrox than on air simply because you will be at deeper depths for longer.

Why do divers enter the water backwards?

The Backward Roll Helps Keep Boats Stable While these boats may have a low center of gravity, a few divers standing on the gunwale will shake things up on board. By entering the water with a backwards fall, you minimize this rocking motion for everyone else on board.

Does nitrox increase bottom time?

As stated, when you dive using nitrox you can take advantage of increasing your maximum allowable bottom time. This happens because the extra oxygen added to your breathing gas when it was filled has displaced nitrogen.

Can you go deeper with nitrox?

You can simply reduce the risks by doing the same dive profile but on Nitrox. Though, you can’t dive deeper with Nitrox! Even if many people may think so. Nitrox is actually inappropriate for deep dives!

Does nitrox make you feel better?

Breathing-gas mixtures with a lower nitrogen content and higher oxygen content (enriched air nitrox) have gained popularity among divers looking to increase their bottom times or reduce the decompression stress of typical-duration dives.
