The most frequent known root cause for diving fatalities is running out of, or low on, breathing gas, but the reasons for this are not specified, probably due to lack of data. Other factors cited include buoyancy control, entanglement or entrapment, rough water, equipment misuse or problems and emergency ascent.
Why do divers not get crushed?
The reason is quite simple: the contents of our bodies (blood, bones, muscle, etc) are at the same pressure as the atmosphere. Even if they were not, atmospheric pressure is certainly not enough to get our bones crushed. When a diver is 10m under water, the pressure is doubled (202650 Pa).
What happens if a diver decompresses too quickly?
And if a diver rises to the surface (decompresses) at the right rate, the nitrogen can slowly and safely leave the body through the lungs. But if a diver rises too quickly, the nitrogen forms bubbles in the body. This can cause tissue and nerve damage.
What are the two major medical problems of specific concern to divers?
Drowning: Any incapacitation while underwater can result in drowning (see Injury & Trauma in this chapter). Nitrogen narcosis: At increasing depths, the partial pressure of nitrogen increases, causing narcosis in all divers. The impairment can be life threatening.
