RELATIONSHIP OF PRESURE TO SEA DEPTH
When we go to deep into sea ,with every 33ft depth ,pressure increases by one atmosphere
A column of seawater 33
ft
deep exerts the same pressure at its bottom as the pressure of the atmosphere above the sea.
At 33ft depth of sea, a person is exposed to 2 atmospheric pressureSlide3Slide4
EFFECT OF HIGH PARTIAL PRESSURES ON BODY
NITROGEN NARCOSIS AT HIGH NITROGEN PRESSURES
OXYGEN TOXICITY AT HIGH PRESSURESlide5
DECOMPRESSION SICKNESS
If a diver remains beneath sea for a long time ,large amount of nitrogen becomes dissolved in his body fluids. When the diver suddenly comes back to sea surface , nitrogen bubbles develop in his ICF, ECF that damage different areas of body especially brain .Slide6Slide7
CLINICAL FEATURES

Dizziness
Paralysis
Chokes or shortness of breath
