EMT Allergy and Anaphylaxis

Front

What is anaphylaxis?

Back

Anaphylaxis is a severe, potentially life-threatening allergic reaction that occurs rapidly after exposure to an allergen.

Front

List common symptoms of anaphylaxis.

Back

Common symptoms include urticaria (hives), stridor, wheezing, hypotension, and tongue swelling.

Front

What is the first-line treatment for anaphylaxis?

Back

The first-line treatment for anaphylaxis is the administration of epinephrine.

Front

What is a biphasic reaction in anaphylaxis?

Back

A biphasic reaction is a recurrence of anaphylaxis symptoms after initial treatment, which can occur hours later.

Front

Why is it important to monitor anaphylaxis patients after treatment?

Back

It is important to monitor for biphasic reactions and ensure that symptoms do not return.

Front

What role does epinephrine play in treating anaphylaxis?

Back

Epinephrine works by constricting blood vessels, increasing heart rate, and opening airways, counteracting the severe effects of anaphylaxis.

Front

What is the significance of tongue swelling in anaphylaxis?

Back

Tongue swelling can obstruct the airway, making it a critical initial airway complication in anaphylaxis.

Front

What should be done if a patient uses their epinephrine auto-injector?

Back

EMS providers should transport the patient immediately without further intervention, as additional doses may not be necessary.

Front

What is hypotension and how is it related to anaphylaxis?

Back

Hypotension is low blood pressure, which can occur during anaphylaxis due to vasodilation and fluid leakage from blood vessels.

Front

What is stridor and why is it a concern in anaphylaxis?

Back

Stridor is a high-pitched wheezing sound indicating airway obstruction, which is a serious concern in anaphylaxis.
