What should pilots do if they experience any sign of decompression sickness?

Pilots experiencing any sign of decompression sickness should descend immediately and seek medical attention. Decompression sickness, often resulting from rapid ascent to high altitudes without adequate preconditioning, can manifest in various symptoms such as joint pain, dizziness, fatigue, or neurological issues. The primary purpose of descending is to reduce ambient pressure and allow the nitrogen that has accumulated in the body to be expelled safely.

Seeking medical attention is critical, as decompression sickness can lead to severe health complications if not treated promptly. Treatments might include hyperbaric oxygen therapy, which is effective in reducing the effects of the condition and facilitating recovery.

Continuing to fly at the same altitude could exacerbate the symptoms and physiological damage, while performing a controlled ascent or waiting for symptoms to resolve on their own does not address the urgent need for immediate pressure reduction and medical intervention. The priority is always the safety and health of the pilot and others regarding any potential aviation-related health issues.
