Which of the following is NOT a treatable cause of cardiac arrest?

Cardiac arrest can occur for various reasons, and it's essential for responders to identify and manage any treatable causes effectively. Among the options presented, hypotension, while a serious condition, is not classified as a direct cause of cardiac arrest in the same way that the other conditions are.

Tension pneumothorax is a life-threatening condition that results in increased pressure in the thoracic cavity, leading to decreased venous return and ultimately cardiac arrest if not treated promptly. Hypovolemia, or significant loss of blood volume, can lead to inadequate perfusion and cardiac arrest as well, making it a treatable cause that requires immediate intervention.

Sepsis, which is a severe systemic infection, can lead to multi-organ dysfunction and potentially cardiac arrest due to its impact on the body’s systemic responses and circulatory dynamics. Each of these conditions—tension pneumothorax, hypovolemia, and sepsis—can be addressed medically to restore normal heart function or prevent an arrest from occurring.

Hypotension, however, while a critical condition that requires management, does not directly cause cardiac arrest. It can result from many underlying issues, but simply having low blood pressure does not make it a treatable cause of cardiac arrest in the same
