How does decompression sickness affect the brain?

Air embolism: The brain is damaged due to lack of oxygen caused by bubbles in the arterial circulation. The bubbles lodge in the small arteries, preventing blood from getting to the brain. The brain can only tolerate lack of oxygen for 5 to 6 minutes, after which it starts to die (stroke).
