Is it advisable to discontinue oxygen first aid when symptoms of decompression sickness disappear?

Discontinuing oxygen first aid when symptoms of decompression sickness have disappeared is not advisable. The rationale behind this is based on the nature of decompression sickness, which can involve the formation of nitrogen bubbles in the body. While the visible symptoms may subside, there could still be bubbles present that need to be managed effectively.

The treatment with supplemental oxygen is crucial because it helps to reduce the size of these bubbles and increases the amount of oxygen available to the tissues, promoting healing and preventing further complications. Maintaining oxygen therapy until a complete assessment and clearance by a medical professional ensures that any residual effects of decompression sickness are adequately addressed. Therefore, oxygen should be provided until a definitive medical evaluation can confirm that the risk of further issues has passed.
