At moderate doses (2-10 mcg/kg/minute), dopamine stimulates beta-1 receptors, which increases myocardial contractility and increases cardiac output. Step 1: Convert weight in pounds to kilograms. 1 kg:2.2 lb = X:176 lb. X = 176 lb/2.2 lb per kg = 80 kg. Step 2: Determine how many micrograms per minute of drug are required for the low and high ends of the range. Low: 2 mcg/kg/min F1F1F1S1F1F1F10 80 kg = 160 mcg/min. High: 10 mcg/kg/min F1F1F1S1F1F1F10 80 kg = 800 mcg/min. Step 3: Convert micrograms per minute to micrograms per hour. Low: 160 mcg/min F1F1F1S1F1F1F10 60 min/hr = 9600 mcg/hr. High: 800 mcg/min F1F1F1S1F1F1F10 60 min/hr = 48,000 mcg/hr. Step 4: Convert micrograms per hour to milligrams per hour. Low: 9600 mcg/hr / 1000 = 9.6 mg/hr. High: 48,000 mcg/hr /1000 = 48 mg/hr.
