Today we are going to talk about lung over expansion injuries and how to treat them. The trend these days is to disregard the issue and believe it only happens to others going deep. Unfortunately, this is a myth. DCS and DCI can occur from only ten meters depth and you, as a going to be Scuba Instructor or Divemaster, need to know how to identify them and how to treat them.

Heat and Water in theory:
As we learned, water absorbs heat faster then air does. But why is that? There are several reasons why heat absorption is greater in water. One of them is that water is denser or has a greater thickness of matter than air. It also means water has more mass = molecules for a given volume. Heat is the energy what gets molecules moving. Hence the denser (more molecules) a substance is, the more energy (heat) it needs, which means it absorbs heat faster then a less denser substance like air for example. Another point is also the bonds within the molecules which are so called weaker or more elastic which needs more energy (heat) to overcome. So to summarize, water needs more heat energy to rise to a given temperature.

Everyone remembers their first dive in the ocean. The first time you dip under the surface and you enter a whole new world. Your first dive could have been a Discover Scuba diver course or it was part of your Open Water Course. Either way if you are reading this blog, you loved it and are now a certified Open Water Diver who loves to dive and wants to take the next step in diving.
