Which of the following is a symptom of air embolism?

Dizziness and impaired vision are indeed classic symptoms of air embolism. An air embolism occurs when air bubbles enter the bloodstream, which can happen during diving if a diver ascends too quickly after spending time at depths where pressure is significantly higher. The presence of air bubbles can disrupt normal blood flow and cause various neurological symptoms due to a lack of proper blood supply to the brain.

Dizziness may manifest as feelings of lightheadedness or a sense of vertigo, which can significantly affect a diver’s ability to maintain control while underwater. Impaired vision, which may include blurred or tunnel vision, occurs due to the bloodstream not effectively delivering oxygen to the optic nerves or brain regions responsible for vision because of the obstruction caused by the bubbles.

Recognizing these symptoms is critical for divers, as they indicate the need for immediate medical attention to prevent serious complications, including stroke or death.
