Term
|
Definition
located in peripheral blood vessels and smooth muscle
if stimulated cause vasoconstriction
if blocked cause vasodilation |
|
|
Term
|
Definition
located inside myocardium
speed the heart (chronotropic) and increase myocardial contractility (inotropic), increasing cardiac efficiency
may also increase cardiac workload |
|
|
Term
|
Definition
located in bronchi, bladder wall, intestine, uterus
relax bladder all, intestine, uterus - vasodilation
broncholation- increases air passage |
|
|
Term
|
Definition
| when stimulated, cause vessels of renal, mesenteric, coronary, and cerebral arteries to dilate, which increases blood flow to these tissues |
|
|
Term
|
Definition
include epinephrine and dopamine
cause vasoconstriction
increase BP- used in critical care units or ER
requries careful monitoring
used for patients with shock or allergic reactions |
|
|
Term
|
Definition
stimulates alpha 1 receptor cells
uses: bradycardia, cardiac arrest, hypotension, anaphylaxis
routes: IV titration, IVP, SC
monitor for mycoardial ischemia, arrhythmias
look strength and concentration because of potential CNS stimulation and adverse effects, along with potential for dependency |
|
|
Term
|
Definition
low dose: dopaminergic receptors; renal perfusion increases
medium dose: beta receptros: stimulates cardiac contractility
high dose: alpha receptors: vasoconstricts |
|
|
Term
| alpha-adrenergic blocking agents |
|
Definition
to treat life threatening cardiovascular conditions
counteract vasopressive drug effects |
|
|
Term
| beta-adrenergic blocking agents |
|
Definition
block beta receptors of SNS
decreases conduction velocity
reduces myocardial oxygen demand
reduces workload of the heart
used for patients with hypertension, glaucoma, anxiety, migraine headache prophylaxis, thyrotoxicosis, arrhythmias, angina, post MI
Contraindications: COPD, bronchospasms, slow heart rhythms, CHF
