Chapter 21 Anaphylactic reactions Flashcards
a type of antigen that produces an abnormally vigorous immune response in which the immune system fights off a perceived threat that would otherwise be harmless to the body.
such as dust mite excretion, pollen, pet dander or even royal jelly
some foods such as peanuts (a legume), nuts, seafood and shellfish are the cause of serious allergies in many people.
allergens
life-threatening allergic reaction
allergic reaction
life-threatening allergic reaction also known as anaphylactic shock and anaphylaxis
anaphylactic reaction
sudden, severe allergic reaction characterized by a sharp drop in blood pressure, urticaria, and breathing difficulties that is caused by exposure to a foreign substance, such as a drug or bee venom, after a preliminary or sensitizing exposure
S/S
dizziness, loss of consciousness, labored breathing, swelling of the tongue and breathing tubes, blueness of the skin, low blood pressure, heart failure, and death.
anaphylactic shock
resembling generalized anaphylaxis but not caused by IgE-mediated allergic reaction but rather by a nonimmunologic mechanism
anaphylactoid reaction
sudden, severe allergic reaction characterized by a sharp drop in blood pressure, urticaria, and breathing difficulties that is caused by exposure to a foreign substance, such as a drug or bee venom, after a preliminary or sensitizing exposure
S/S
dizziness, loss of consciousness, labored breathing, swelling of the tongue and breathing tubes, blueness of the skin, low blood pressure, heart failure, and death.
anaphylaxis
are proteins that exist in bodily fluids, and are used both as a detection and response device by the immune system
antibodies
the substance that binds specifically to the respective antibody
antigen
a medical device designed to deliver a single dose of a particular (typically life-saving) drug.
auto-injector
usually simply referred to as intubation, is the placement of a flexible plastic tube into the trachea (windpipe) to maintain an open airway
endotracheal intubation
also known as adrenalin is a chemical that narrows blood vessels and opens airways in the lungs
epinephrine
a substance present in cells of the immune system. It is released when tissue is damaged and during an allergic reaction
histamine
1st exposure to a an allergen
hypersensitivity
is how your body recognizes and defends itself against bacteria, viruses, and substances that appear foreign and harmful
immune response
biological structures and processes within an organism that protects against disease.
