FAQ

Those interested in the Air nitrox diving category often ask the following questions:

🌊 Is diving with nitrox dangerous?

One dangerous symptom of oxygen toxicity is uncontrollable convulsions, which in diving usually leads to loss of the regulator and death by drowning. To reduce the risk of oxygen toxicity when using enriched air nitrox, scuba divers must monitor both their depth and total exposure to oxygen over a series of dives.

🌊 What does nitrox ready mean in diving?

  • The Nitrox-ready dive computer is for Nitrox Diving to take account of the specific Nitrox gas mix you use on the dive. Your special Nitrox computer will take account of the higher concentration of oxygen when calculating maximum depths and bottom times.

🌊 What is nitrox used for in diving?

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.

🌊 Why is nitrox used when scuba diving?

  • Enriched Air Nitrox, nitrox with an oxygen content above 21%, is mainly used in scuba diving to reduce the proportion of nitrogen in the breathing gas mixture. The main benefit is reduced decompression risk.

🌊 What are the advantages of nitrox diving?

  • The advantages of diving with Nitrox is not from the added oxygen you breath in but rather, the lower percentage of nitrogen you consume. Here are some advantages of diving with Nitrox: Because you are breathing air with a lower percentage of nitrogen, there will be less nitrogen for your body to absorb.

Can you dive deeper with nitrox?

So how deep can you dive with nitrox? With 32% nitrox you can dive to a maximum depth of 33 metres (110 feet). Whereas with 36% nitrox this reduces to 28 metres (90 feet). Nitrox extends your dive time and in some cases is nearly double that of atmospheric air at the maximum dive depths for nitrox.

How is air put into diving tanks?

How does the air in a scuba tank work?

  • Generally speaking, this is the makeup of the air that fills a diver’s tank; the only difference is that the air in the tank is compressed, allowing underwater breathing for a prescribed amount of time. Because our body needs it for its metabolic function, the air in a SCUBA tank cannot be devoid of oxygen.

How air embolism happens in scuba diving?

  • This ventilator could force air into a damaged vein or artery. You can also get an air embolism while scuba diving. This is possible if you hold your breath for too long when you’re under water or if you surface from the water too quickly. These actions can cause the air sacs in your lungs, called alveoli, to rupture.

How much air changes in a diving bell?

Why does a diving bell have to be heavy?

  • The reason it needed to be so heavy was because of the resistance you feel when you push the cup into the water. The force of the water pushes the air up, compressing it as water enters the bottom of the open bell. While there is some water in the bottom of the bell, the bulk of it remains packed with breathable air.

What's the difference between nitrox and ead scuba?

  • At 60 feet, the diver's maximum time would be one hour. Nitrox changes the numbers. When you replace some of the nitrogen with extra oxygen, there's less nitrogen available, which means it won't dissolve as quickly, allowing a longer no-decompression limit. This concept is known as the equivalent air depth (EAD).
