Question 1

What is decompression sickness?

Accepted Answer

Decompression sickness, also known as "the bends," occurs when a diver ascends too quickly, causing nitrogen bubbles in the bloodstream. To prevent it, divers should follow proper ascent rates, plan their dives carefully, and adhere to decompression guidelines by making decompression stops during ascent to allow the body to release excess nitrogen safely.

Question 2

How can I prevent barotrauma during scuba diving?

Accepted Answer

Barotrauma can be prevented by ensuring proper equalization of pressure during descent, using techniques such as swallowing, yawning, or performing the Valsalva maneuver to equalize pressure in the ears and sinuses. Controlled and gradual ascents can also help prevent lung overexpansion and potential air embolism.

Question 3

What is nitrogen narcosis?

Accepted Answer

Nitrogen narcosis, or "the rapture of the deep," is a condition that impairs judgment and cognitive function in divers at certain depths. To manage nitrogen narcosis, divers should limit dive depths according to their training and experience and perform regular buddy checks to ensure mutual monitoring and assistance during dives.

Question 4

How can I reduce the risk of drowning while scuba diving?

Accepted Answer

Drowning incidents during scuba diving can be minimized by maintaining vigilance, receiving proper training, and diving within limits. Divers should regularly monitor their air supply, practice emergency ascent procedures, and follow the buddy system to ensure mutual safety.
