Study Notes
- Dobutamine (Dobutrex) is a synthetic sympathetic agonist.
- Lidocaine drip rate is 1-4mg per minute.
- Dopamine drip rate is 5-20 mcg/kg/min.
- Dopamine is administered to treat bradycardia and hypotension.
- Fentanyl decreases cardiac oxygen demand.
- Diuretics reduce circulating blood volume in the kidneys.
- Antiarrhythmics affect the heart's electrical activity to regulate heart rhythm
- Beta blockers and ACE inhibitors are important classes of medications to study
