7
Q
Dopamine receptors
A
DA1 (low)
B1 (med)
A1 (high)
8
Q
Dopamine high dose
A
B1 receptor stimulation: increases Cardiac contractility and HR leading to increase in Bp
A receptors : vasoconstriction
9
Q
Dopamine low dose
A
DA receptors stimulation in the mesmeric, renal and coronary beds resulting in vasodilation ( renal dose)
10
Q
Dobutamine how it works
A
Improved contractility without increased HR and SVR (systemic vascular resistance)
11
Q
When is Metaraminol used
A
Acute hypotension
12

A
Shock (carcinogenic), cardiac arrest, bronchospasm, symptomatic bradycardia
