Which two body systems should be evaluated for a severe anaphylactic reaction?

The correct answer highlights the critical importance of assessing the airway/respiratory and cardiovascular systems during a severe anaphylactic reaction. Anaphylaxis is a life-threatening allergic reaction that can lead to significant airway obstruction and cardiovascular collapse.

In the respiratory system, the rapid onset of symptoms such as swelling of the airway passages, bronchospasm, and difficulty breathing can occur. These changes can lead to inadequate oxygen exchange and respiratory failure if not promptly recognized and treated.

Simultaneously, anaphylaxis can cause a profound cardiovascular response, which may include a drop in blood pressure due to vasodilation and increased heart rate, potentially leading to shock. Monitoring for signs of cardiovascular compromise, including changes in blood pressure and heart rhythm, is essential in the management of a patient experiencing anaphylaxis.

By focusing on these two systems, EMTs can quickly identify life-threatening complications and intervene appropriately to stabilize the patient. This dual assessment helps ensure that both breathing and circulation are supported, which is crucial in the rapid treatment of anaphylactic reactions.
