What the heck? Partial Pressure Explained … Partial pressure is a term used in gas laws. Without getting into a physics lesson, in a gas mixture, each gas has a partial pressure which is equal to the fraction of gas represented in the mix multiplied by the pressure.
As a Nitrox Diver, you have to understand Oxygen Toxicity At this point, you have to be asking, why didn’t I hear about the adverse effects of oxygen in my Open Water or Beginner Scuba Diver certification class? Good question; and some agencies are changing that and making it a part of the beginner lesson […]

What is Nitrox and why does it matter to me?
As human beings, we are used to breathing a nitrogen/oxygen mix. In fact, our atmosphere is primarily made up of these two gases. Right now, you are breathing a gas mixture known as air, which is comprised of approximately 79% nitrogen and 21% oxygen. Oxygen is what you need. Nitrogen is relatively inert and does not affect us at all, until we go underwater. As you learned in your Open Water Course, too much nitrogen is a bad thing. So that is why we look at Nitrox as a substitute to diving air. Enriched air (commonly referred to as Nitrox) is a nitrogen/oxygen mix that has more oxygen than 21% and less nitrogen than 79%. More oxygen and less Nitrogen means you can safely extend your bottom time while absorbing less nitrogen. What diver doesn’t want more bottom time? If you would like to know more, you can read through our general information section, however we also recommend taking one of our Nitrox courses.
