- Critical care : Health care provided to a critically ill patient during a medical emergency or crisis.
- Emergency medicine : Emergency medicine is both a specific medical specialty dealing with the proper care of patients with unexpected injuries or disease, but also the provision of entire systems for such care, beginning with minimal bystander assistance, through field medicine, emergency rooms and trauma centers, and movement to specialized facilities such as burn units and interventional neuroradiology
- Immunology : The study of all aspects of the immune system in all animals.
- Respiratory emergencies : Medically established procedures for assessment and management of potentially life-threatening conditions involving the respiratory system, with appropriate anatomical, physiological, and pathological context
- Atopy : Add brief definition or description
- Basophil : A circulating leukocyte which, when sensitized to a specific antigen by means of an immunoglobulin E molecule bound to its surface, will release physiologically potent chemicals on recognizing that antigen
- Beta-adrenergic agonist : Add brief definition or description
- Beta-adrenergic antagonist : Add brief definition or description
- Dopamine : A monoamine neurotransmitter formed in the brain by the decarboxylation of dopa and essential to the normal functioning of the central nervous system.
- Histamine antagonist : A member of a class of drug that binds to cell surface receptors for histamine1, histamine2, and histamine3 receptors, preventing them from activating. The receptor types have a variety of functions; histamine1 activities include allergic reactions and nausea, histamine2 reduce gastric acid secretion and relax smooth muscle, and histamine3, still in research, have central nervous system effects. "Antihistamines" are most often histamine1 blockers.
- Endotracheal intubation : Add brief definition or description
- Epinephrine : A hormone (adrenalin) adrenergic systems-stimulator used in asthma and cardiac failure.
- Glucagon : Add brief definition or description
- Histamine : A biogenic amine involved in local immune responses as well as regulating physiological function in the gut and acting as a neurotransmitter.
- Immunoglobulin : Proteins produced by lymphocytes, which are primarily antibodies to attack material the body considers hostile, although some may act as cytokines, signaling to other cells
- Mast cell : Non-circulating, but leukocyte-like (especially basophil) associated with the inflammatory response, especially the release of histamine.
