What is the first aid procedure for decompression illness?

If you suspect someone is experiencing decompression illness:

*Administer oxygen: Provide the person with 100% oxygen; this can help improve their condition.

Descend: If possible, descend the person back to the depth at which they were last symptom-free. This can help reduce the pressure on their body and stop the nitrogen bubbles from expanding.

Recompression therapy: This is the definitive treatment for decompression illness and involves placing the person in a hyperbaric chamber and gradually increasing the pressure. This helps to reduce the size of the nitrogen bubbles and allows the body to reabsorb them.

Monitor the person: Keep a close eye on the person's condition and monitor their vital signs. If their condition deteriorates, seek medical assistance immediately.

Note: It's crucial to seek professional medical assistance for decompression illness as soon as possible. While initial first aid measures can help temporarily alleviate symptoms, proper treatment in a hyperbaric chamber is essential for complete recovery.
