What is a common symptom of chokes respiratory decompression sickness?

Difficulty breathing is a common symptom of chokes respiratory decompression sickness, which occurs when a diver ascends too quickly after being at depths underwater. This condition is primarily caused by nitrogen bubbles forming in the bloodstream and tissues due to a rapid decrease in pressure. The formation of these bubbles can obstruct blood flow in the lungs, leading to respiratory distress and difficulty in breathing.

In this context, the other symptoms listed, such as sensory deficits, joint pain, and skin rashes, may be associated with decompression sickness but are not specifically hallmark signs of respiratory involvement, which is why difficulty breathing stands out as the most relevant and immediate concern in cases of chokes. This symptom directly relates to the physiological changes that occur when nitrogen bubbles affect the respiratory system, making it a critical point for those trained in advanced trauma and emergency procedures during underwater rescue scenarios.
