Which symptoms may indicate anaphylaxis that an EMD should recognize?

The symptoms listed in the selected answer are critical indicators of anaphylaxis, a severe allergic reaction that can be life-threatening. An Emergency Medical Dispatcher (EMD) must be trained to recognize these symptoms quickly to ensure prompt and appropriate emergency response.

Swelling of the face and throat can obstruct airways, making it difficult for an individual to breathe. This is a hallmark of anaphylaxis, indicating that the body is experiencing a severe reaction. Difficulty breathing can manifest as wheezing, stridor, or a sense of tightness in the chest, all of which require immediate medical intervention. Hives, or urticaria, are also commonly associated with allergic reactions and can appear as raised, itchy welts on the skin, further corroborating the presence of a severe allergic response.

Recognizing these specific symptoms allows the EMD to prioritize the call and provide instructions for the caller to take steps while awaiting emergency services, such as utilizing an epinephrine auto-injector if available. Awareness of these signs is crucial to prevent the rapid deterioration of the patient's condition due to anaphylaxis, emphasizing the vital role of the EMD in the emergency response chain.
