The life-threatening allergic reaction.
The body'd defense mechanism against foreign substances (antigens), including those that cause allergic reactions (allergens)
Production of antibodies to fight foreign substances. An allergic reaction or life-threatening anaphylactic reaction(anaphylactic shock; anaphylaxis) is an abnormal response.
Altered reactivity to an allergen that causes an allergic reaction, after the sensitization (the process of developing hypersensitivity on first exposure to an antigen) that occurs in the first exposure.
- Chemical mediator, released from mast cells, in an anaphylactic reaction.
- Causes bronchoconstriction, vasodilation, and an increase in capillary permeability (leakage)
- Reaction similar to an anaphylactic reaction that may occur on the first exposure without prior sensitization.
- Signs and symptoms are the same.
- The primary difference will be that the patient will never have a previous exposure.
A general feeling of weakness or discomfort.
- Placement of a tube down the trachea to facilitate airflow to the lungs.
- Provided by ALS
Raised bed blotches associated with allergic and anaphylactic reactions
- A natural hormone that, when used as a medication, constricts blood vessels to improve blood pressure, reduces leakage from blood vessels, and relaxes smooth muscle in the bronchioles.
- Both an alpha and beta drug
