Which of the following is a possible sign of AGE?

Dizziness can indeed be a possible sign of Arterial Gas Embolism (AGE), which occurs when gas bubbles enter the arterial bloodstream, leading to various neurological and physical symptoms. The presence of dizziness may result from reduced blood flow to the brain or other areas affected by gas bubbles.

Understanding AGE is crucial for divers, as it can lead to serious complications. The other symptoms listed, like severe headache, muscle spasms, and nausea, can also correspond with various conditions, including decompression sickness or other medical issues, but they are not specifically indicative of AGE. In terms of diagnosis and treatment, recognizing signs closely associated with AGE, such as dizziness, is vital for prompt intervention and management of the condition.
