Basic Physiology of Scuba Diving

If you read the physics page first on pressure this page will make more sense (See: Dive Physics)

As human beings we are made mostly of water and as you may be aware, water is almost incompressible... However, as humans we also have air spaces in our bodies that are very sensitive to even minor changes in pressure. Our Ears and middle ear in particular are such spaces.

Medical problems associated with pressure trauma are referred to as hyperbaric injuries. Although these can be serious in nature they are also very simple to avoid by obeying a few simple rules...

1. Descend and Ascend Slowly and be "Comfortable"....
2. On ascent stop approx 5-6m from the surface for 3-5mins
3. If diving deeper than 20m/66ft. We recommend two(2) stops, 1 at 9m for 2-3mins and 2. at 6m for 3-5mins. (Longer at the last stop is better)
4. Equalise your air spaces on descent, early and often (Your Comfort is the key factor) Nose / Mask Spaces MUST be equalised for comfort or pain may occur.
5. Ascend no faster than 9m./30ft. per minute, and generally slower is better, unless you are a technical diver ascending from very deep water...
6. Use the Dive Tables to plan and execute your dives to your exact profile
7. Conduct a risk assessment before each dive based on your skills, training and experience. (And include your buddy or other dive group members)

As you can see there is not a great deal to remember but the practice, and training is vital to developing "Safer Diving Skills", and good diving habits. See: Dive Tables

There are many other physiological implications involved in Scuba diving but we have sought to give you just a taste of the value and importance of a basic understanding of diving physiology here, if you would like more information please email us.
