Monitoring breathing and pulse is essential in the event of an arterial gas embolism (AGE). When a diver experiences AGE, gas bubbles can form in the bloodstream and impede blood flow, potentially leading to serious health risks. By closely observing breathing patterns and pulse rate, divers can identify signs of distress or changes in their physiological state that may indicate an embolism.

In the context of diving, a rapid or irregular pulse may suggest that the body is under stress, and changes in breathing could indicate that normal gas exchange is compromised. Therefore, these vital signs are crucial indicators of the diver's wellbeing and can help in determining if immediate assistance is needed.

This focus on vital signs is vital in managing emergencies in diving scenarios, as prompt recognition and response can be lifesaving. Other factors like surrounding marine life, depth and time, and water temperature, while important in the overall context of diving safety, do not directly aid in monitoring the potential effects of an AGE.
