If divers using air (containing approximately 78% nitrogen and 21% oxygen), then the nitrogen will dissolve in the blood. This occurs because the solubility of gases in liquids is directly proportional to the pressure.
As you know, the pressure at depths greater than surface pressure. Well, when the divers return to the surface, the nitrogen dissolved in the blood was coming out to form bubbles, much like the coca cola bottle is opened. This caused pain extraordinary known as the bends (bend, because people will bow because of pain). Bends can be prevented if used Natural mixture of helium - oxygen, because helium is less soluble in blood. In addition, nitrogen at high pressure will provide narkosa effect, which will affect the diver in taking decisions, so that accidents often occur due to carelessness.

jd bkn oksigen murni?
yang g ada jwbnny d atas,knp hrs pake cmpuran?
kalo gak pake campuran saat menyelam, O2 pada tekanan yang tinggi bisa menyebabkan keracunan (Oxygen toxicity) yang menyebabkan kerusakan sel2 tubuh.
hla kowe ws tau nyelem durung Osh?
dadi penasaran...
mbuh pye keracunan oksigen kuwi, aku yo mung maca tapi ra ngerti..
ws tak bdek...
