Nitroprusside purpose - Answer- decreases preload and afterload by vasodilation (mainly afterload) Dobutamine mechanism of action - Answer- contractility Dopamine at a low-end dose "renal dose" - Answer- 0.5-4mcg/kg/min increases renal and mesentric perfusion Dopamine at a mid-range dose - Answer- 4-10mcg/kg/min increases contractility and heart rate Dopamine at a high-range dose - Answer- greater than 10mcg/kg/min vasoconstriction and increases BP Dopamine and Levophed inf...

2 parameters that can be measured with pulmonary artery catheter: - 1) pulmonary artery wedge pressure (PACapillaryP) AKA Pulmonary artery occlusive pressure (PAOP) 2) Pulmonary artery diastolic pressure (PADP) A cholinergic response is seen with which part of the autonomic nervous system? - parasympathetic (acetylcholine - produces negative dromotropic and chronotropic effects on the heart) A person who has had a previous MI will likely exhibit what finding on an EKG? - bundle branch blo...

Cardiac output = Ans- CO + HR x stroke volume (amount of blood ejected per contraction) Primary compensatory mechanism of low Cardiac output in peds? Other signs? Ans- Tachycardia -- Peds are unable to increase stroke volume. Hypotension is a late sign, and bradycardia is an ominous sign in peds. Stroke Volume is influenced by... Ans- Contractility, preload, and afterload. Frank-Starling's Law -- Stretch heart with volume to increase contractility (rubber band snapping shut) Preload...
