Which of the following are signs of decompression sickness?

Decompression sickness, often referred to as "the bends," occurs when divers ascend too quickly, resulting in the formation of nitrogen bubbles in the bloodstream and tissues. The signs of this condition can vary in severity and manifestation.

Pain in the torso is a common symptom, often presenting as deep, aching pain in the joints and muscles, which can also affect the torso. This is one of the hallmark signs that divers may experiences.

Staggering, which implies difficulty in maintaining balance, can indicate neurological impact from decompression sickness. It results from the gas bubbles interfering with the nervous system, which can lead to coordination and balance issues.

Dizziness is another potential symptom, as the presence of gas bubbles can disturb blood flow and affect how well the brain is receiving oxygen, leading to lightheadedness or disorientation.

Given that all these symptoms—pain in the torso, staggering, and dizziness—can occur as a result of decompression sickness, the correct answer encompasses all of them, confirming that the recognition of these signs is crucial for early detection and treatment of the condition.
