What is type 2 decompression sickness characterized by?

It's less serious than type 1.
It's caused by the gathering of nitrogen bubbles in the CNS, lungs, or heart.
It primarily results from rapid ascent in diving.
It only affects the skin.

The correct answer is: It's caused by the gathering of nitrogen bubbles in the CNS, lungs, or heart.

Type 2 decompression sickness is characterized by the accumulation of nitrogen bubbles in critical areas of the body, particularly the central nervous system (CNS), lungs, or heart. This condition arises when divers ascend too quickly after being at depths that require decompression, leading to a rapid reduction in pressure that causes the dissolved nitrogen in their tissues to form bubbles. This type of decompression sickness is more serious than type 1 because it can lead to severe complications, including neurological damage or respiratory distress due to bubbles obstructing blood vessels in the CNS or lungs. The involvement of these vital organs sets type 2 apart as a more acute medical emergency and emphasizes the importance of adhering to safe diving practices to prevent this dangerous condition.
