What is FO2 in diving?

Why is nitrox better for diving?

The benefit of using nitrox instead of regular gas is that it helps increase your allowed diving time as it offers less nitrogen (and more oxygen) for you to inhale, thus reducing the amount of nitrogen that will quickly dissolve into your body—thereby lengthening your no-decompression limit.

What does 1.4 mean in diving?

For safety reasons, 1.4ata is considered the maximum safe partial pressure. When we are diving 21%, 1.4ata is reached at around 185 feet/56 meters. This is much deeper than we can dive due to the effects of nitrogen. However, if we switch to EAN-36 we will hit the 1.4ata safety limit at only 94 feet/ 28 meters.

What should I set my PO2 to?

While different dive computers have different default settings for both the oxygen percentage in the mix and the maximum PO2, most default settings tend to be conservative. In many cases, the default setting for the percentage of oxygen will be 21% while the default setting for PO2 is often 1.4.

How deep can I dive with nitrox?

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.

What is nitrox good for?

Like everything else in a diver’s bag of gear and knowledge — nitrox is a tool that can be effective when used properly, but dangerous if not. Its purpose is to increase your no stop dive time, so you have longer dives and/or shorter surface intervals, all else being equal and gas supply allowing.

Is nitrox better than air?

Nitrox allows you to spend more time at depth compared to diving on air, which means you’ll get a lot more out of your diving holiday. Even if you’re only making one dive, but it’s deeper than 15 metres/50 feet, nitrox is beneficial.

At what depth do you need to decompress?

The deeper and longer your dive the more chance you need decompression stops. Shallow dives of 6-10 metres (20-30 feet) you can spend over 200 minutes without a decompression stop. Dives to over 30 metres (100 feet) limit your dive time to around 20 minutes before a decompression stop is required.

How fast can you ascend diving?

You should never exceed an ascent rate of 10m/minute when diving shallower than about 30m. . An ascent rate of 5-6 metres per minute is recommended in the last 10m of ascent. Complete safety stops on all dives that exceed 10m depth.
