I have wanted to make my own nitrox sticker for some time. They are used on scuba tanks to show that a mixture in the scuba made contain a mixture that has more oxygen than air. The plus side of nitrox is that you are breathing less nitrogen under pressure and than means your body is absorbing less N2. This will reduce the negative effects of nitrogen such as nitrogen narcosis and the bends.
The drawback is that the extra oxygen can cause a different set of problems called oxygen toxicity. That is when you absorb too much oxygen. Like many things in life, scuba diving is a balancing act and you need to factor many things into your decisions.
I’ve ordered the stickers and I’ll post what they look like as soon as I get them.
