What are the potential first aid measures for decompression sickness?

• A. Immobilizing the patient and cooling them down
• B. Administering pure oxygen and treating for shock
• C. Encouraging movement to stimulate blood flow
• D. Using ice packs to reduce swelling

Answer: (B)

Administering pure oxygen and treating for shock is a critical response in cases of decompression sickness. Pure oxygen helps to reduce the volume of nitrogen bubbles that form in the tissue and bloodstream after a diver ascends too quickly. By providing high concentrations of oxygen, the body's tissues can eliminate dissolved gases more effectively, essentially assisting the body in reabsorbing the nitrogen bubbles and minimizing symptoms. Additionally, treating for shock is vital since decompression sickness can lead to symptoms such as low blood pressure and confusion. Ensuring the patient is stable and receiving appropriate medical care is essential before transporting them to a medical facility for hyperbaric oxygen therapy, which is often the definitive treatment for severe cases. While immobilizing the patient can be part of general first aid practices, it is the combination of pure oxygen and shock treatment that addresses the specific physiological challenges of decompression sickness effectively.
