What is the recommended action when experiencing symptoms of DCS Type II?

When experiencing symptoms of Decompression Sickness (DCS) Type II, seeking immediate medical assistance is crucial. DCS type II can manifest with more severe and systemic symptoms, including neurological issues such as paralysis, altered consciousness, or respiratory problems. These symptoms indicate a serious condition that requires prompt evaluation and treatment by medical professionals who are trained in hyperbaric medicine.

Immediate medical intervention is essential because DCS type II can lead to long-term complications or even be life-threatening if not treated quickly. Medical professionals may employ hyperbaric oxygen therapy, which is often necessary to effectively treat the condition. This treatment helps to reduce the size of nitrogen bubbles in the body and enhances oxygen delivery to tissues, promoting healing and reducing potential damage.

The other actions, such as resting and hydrating, continuing to dive with caution, or performing an emergency ascent, do not adequately address the severity of DCS Type II symptoms and may even worsen the condition. Therefore, the priority should always be to consult with medical personnel when such symptoms are present.
