Premergency First Aid, CPR and AED Manual

3 Airway and Breathing

Severe Allergic Reaction – Anaphylaxis A life threat to the airway and breathing can result from a severe allergic reaction called anaphylaxis. Anaphylaxis commonly causes airway swelling and low blood pressure. In severe cases the airway may swell so much that a breathing problem can range from difficulty breathing to complete airway obstruction. Anaphylaxis can also affect the skin and intestinal system. Anaphylaxis usually occurs when a person is exposed to an “allergen substance” that they are very sensitive to. Symptoms can develop over a number of hours after exposure but the most severe reactions usually happen within minutes. A reaction can be caused by anything - from eating a certain food, an insect sting, or even a medicine. Many patients with an allergy known to cause a severe anaphylactic reaction will have prescribed emergency

medication in the form of an epinephrine auto injector or “epi-pen”. This device automatically delivers a dose of epinephrine through a concealed, spring-loaded needle mechanism. In the event of a severe anaphylaxis reaction, the patient may require your help in taking their medication. Read and follow the directions. Auto injectors will work through most light and medium weight clothing. Heavy outer layers should be removed prior to using.

* Another injection medication source for Anaphylaxis is “Twinject” , however, it has been discontinued in Canada since 2013.
