Final answer:
Anaphylactic shock, or anaphylaxis, is a severe and rapid allergic reaction that can lead to life-threatening symptoms such as low blood pressure and respiratory distress. It is commonly treated with epinephrine, often administered with an EpiPen®, which is essential to carry for individuals with severe allergies.
Step-by-step explanation:
Anaphylactic shock, also known as anaphylaxis, is a systemic and potentially life-threatening type I hypersensitivity reaction that occurs rapidly when an individual who is allergic to a specific substance is exposed to it. This exposure can be through ingestion, injection, or inhalation of the allergen, which leads to systemic mast cell degranulation. Consequences include a severe drop in blood pressure, contractions of bronchial smooth muscle leading to respiratory distress, and potentially fatal outcomes if not treated swiftly.
The treatment for anaphylaxis is the immediate administration of epinephrine, which can be life-saving. Epinephrine works by raising blood pressure, relaxing bronchial smooth muscles to improve breathing, and modulating heart rate. This counteracts the severe allergic response, and individuals with known severe allergies are advised to carry an automatic epinephrine injector, like an EpiPen®, at all times, particularly when away from hospitals.
Anaphylactic shock, also known as anaphylaxis, is a severe and potentially life-threatening allergic reaction. It is a type I hypersensitivity reaction that occurs when the immune system overreacts to an allergen. The reaction is characterized by a drop in blood pressure, constriction of bronchial smooth muscle, and swelling of the throat, which can lead to respiratory distress and suffocation. If untreated, anaphylactic shock can be fatal within 20 to 30 minutes. Immediate treatment with epinephrine is crucial to counteract the effects of anaphylaxis and save lives.
