What are agonal gasps?

Agonal gasps are defined as abnormal respirations that can occur in the moments following a cardiac arrest. These gasps are not considered normal breathing patterns; rather, they are irregular, ineffective attempts to breathe that often occur sporadically. They may include shallow, labored, or gasping breaths, and they can sometimes be mistaken for normal breathing by untrained bystanders.

It is crucial to recognize agonal gasps as a sign of a medical emergency, as they indicate that the person is in a critical state, typically related to a lack of oxygen and impending brain damage. This is a key reason why immediate intervention, such as calling emergency services and beginning CPR, is essential when these gasps are observed. Understanding the nature of agonal gasps can help bystanders respond appropriately and potentially save a life.
