An air (gas) embolism is clinically similar to what non-diving related medical condition?

An air embolism occurs when gas bubbles enter the bloodstream, potentially blocking blood vessels and leading to serious health complications. Clinically, an air embolism can produce symptoms similar to those of a stroke, such as sudden onset of neurological deficits, which can include weakness, numbness, difficulty speaking, and loss of coordination. These symptoms arise because the embolism can affect blood flow to the brain, leading to similar ischemic conditions that occur during a stroke.

The other medical conditions listed do not share the same clinical presentation as a stroke caused by an air embolism. A dislocated shoulder primarily involves musculoskeletal issues rather than neurological symptoms. A heart attack is associated with chest pain and other systemic symptoms related to cardiac function, while a broken back is also primarily a musculoskeletal injury with different symptomatology focusing on pain and mobility impairment rather than neurological deficits. Thus, the similarity of air embolism and stroke lies in the potential for disruption of blood flow and subsequent neurological impacts.
