What symptom might also be noticed in the mouth of someone suffering from an air embolism?

Bloody froth might be noticed in the mouth of someone suffering from an air embolism because this condition can lead to serious disruptions in the circulatory system. An air embolism occurs when air bubbles enter the bloodstream and can block blood vessels. This obstruction can cause tissue damage and bleeding, which might manifest as bloody froth when the individual coughs or breaths out. The presence of blood in the mouth during such a serious medical emergency indicates a critical situation and is a symptom that requires immediate attention. The other symptoms, while possible in various scenarios, are less directly associated with the physiological effects of an air embolism, making bloody froth a more specific indicator in this context.
