gas embolism theory

Gas embolism occurs when gas bubbles enter the bloodstream and block blood vessels, which can lead to serious health issues. This can happen during diving, where rapid ascent causes nitrogen, dissolved in body tissues, to form bubbles as pressure decreases. These bubbles can obstruct blood flow, causing symptoms like pain, dizziness, or even loss of consciousness. In medical contexts, it can also occur during surgeries if air enters veins. Treatment often involves recompression or administering oxygen to help remove the gas and reduce the risk of tissue damage.
