What causes AGE in divers?

What causes AGE in divers?

• A. Failure to check equipment
• B. Failure to release expanding gas through proper respiration
• C. Rushing through the dive
• D. Ignoring dive tables

Answer: (B)

AGE, or Arterial Gas Embolism, occurs when expanding gases enter the bloodstream, typically as a result of improper breath-holding during ascent. During a dive, divers inhale gases under pressure, which dissolve into bodily tissues and fluids. As a diver ascends, the pressure decreases, and these gases can expand. If a diver fails to exhale adequately while ascending—particularly if they are holding their breath—the expanding gas can cause ruptures in the lung tissues. This results in gas bubbles entering the bloodstream, leading to an embolism. Understanding this physiology highlights why proper respiration is crucial during an ascent. When divers breathe normally, they can effectively release expanding gases, which mitigates the risk of AGE. Therefore, the connection between failure to release gas through proper respiration and the development of AGE underscores the significance of exhaling during ascent to allow for safe decompression.
