What should be done first when treating a diver with Type I symptoms in recompression chambers?

In the case of a diver exhibiting Type I symptoms, the first priority is to perform a medical examination. This is crucial because Type I decompression sickness, also known as "the bends," can manifest with a variety of symptoms affecting different bodily systems. Conducting a thorough medical examination allows healthcare providers to assess the severity of the symptoms and determine the appropriate course of action that aligns with the diver's specific condition.

Identifying the exact symptoms and understanding their implications is critical before any treatment begins. This examination will facilitate informed decisions regarding the need for recompression and the level of medical intervention required. It sets the foundation for effective and safe treatment in the recompression chamber.

In contrast, administering IV fluids or placing the diver on supplemental air may be necessary later, but these actions should follow the initial assessment. Similarly, starting decompression at the surface without fully understanding the diver's condition could exacerbate their symptoms or lead to improper treatment. The initial medical examination is foundational to ensuring the diver receives optimal care tailored to their needs.
