causes of increased MPAP

volume infusion, pulmonary vasoconstriction, decreased LV contractility, hypervolemia, hypoxia, COPD, Pulmonary hypertension

32

causes of decreased MPAP

diuretics, pulmonary vasodilation, inotropic therapy (milrinone and dobutamine) hypovolemia

33

beta receptors are what type of medication

inotrope

34

Beta 1 receptors are found primarily in the

heart

35

beta 1 receptors produces increased -- and --

heart rate and contractility

36

example of beta 1 receptors

dobutamine

37

a1 receptors are found primarily in the

lungs, peripheral arterioles

38

stimulation of a1 produces

constriction of the smooth muscle

39

alpha 2 receptors are found primarily

in the brain

40

stimulation of alpha 2 receptors

promote bronchodilation and block vasoconstriction

41

Dopaminergic receptors are found in

renal, mesenteric, and vascular beds

42

stimulation of dopaminergic receptors produce

vasodilation
