Why are allergic reactions important for EMS to identify and respond to quickly?

Allergic reactions are critical for EMS to identify and respond to quickly because they can lead to airway obstruction, which may occur in a matter of minutes and can be life-threatening. During an anaphylactic reaction, the body releases a cascade of chemicals that can cause swelling of the airway, leading to difficulty breathing or complete airway closure. This rapid progression underscores the urgency of recognizing the signs of an allergic reaction, such as difficulty breathing, swelling of the throat or tongue, or wheezing. Immediate intervention, including the administration of epinephrine, can be life-saving in these situations. The potential for airway compromise and the associated risks highlight why timely and effective response from EMS is essential in cases of severe allergic reactions.
