How can the team minimize the risk of decompression sickness?

• A. By preventing rapid ascent and managing ascent rates appropriately
• B. By ensuring the patient is hydrated
• C. By limiting the weight of cargo
• D. By providing supplemental oxygen only at high altitudes

Answer: (A)

Minimizing the risk of decompression sickness is critically important in any air transport situation, particularly when dealing with patients who may already have compromised health. The correct approach involves managing ascent rates properly. When ascending to higher altitudes, the decrease in ambient pressure can lead to the formation of nitrogen bubbles in the bloodstream, which is the underlying cause of decompression sickness. By preventing rapid ascent and allowing for a controlled ascent rate, the team can facilitate a gradual reduction in pressure on the body. This allows nitrogen that has been dissolved in the blood to be exhaled rather than forming bubbles, thereby reducing the likelihood of decompression sickness occurring. While staying hydrated, keeping cargo weight manageable, and providing supplemental oxygen can contribute to overall patient care and safety, these strategies do not directly address the mechanics of how decompression sickness occurs or effectively mitigate its risk during ascent. The correct answer focuses specifically on the ascent rate, which is the key factor in preventing the condition.
