Problem during diving in the sea: nitrogen narcosis & Caisson disease

When you diving into deep sea, this 2 problems will come out, but there are solutions for you.

1. Nitrogen narcosis occur when you diving more tha 80m, nitrogen gas will dissolve into body tissue especially in fat and also nervous tissue. This cause interference in transfer of signal across the neural synapses.this effect mental, physical and finally cause unconsciousness. But if you want to diving more deeper, you can replace nitrogen with helium, but its still has limitation until 150m. if you go deeper, another complication will occur which is neuromuscular disorder called high-pressure nervous syndrome (HPVS): tremors, vertigo and nausea.
2. Caisson disease is a decompression disease which occur when you rapid come out from deep water. When you diving for every 10 m, air pressure will increase 100kPa causing increase nitrogen gas dissolves especially in fat. Nitrogen gas metabolize slower than other gases that why when you rapid coming out from deep water, nitrogen bubbles will formed
