"I just want to let you know that as an ICU nurse, it is impiortant to know alot about the different dips and how they function. For example if someone has dopamine and levo going and they have a high heart rate and still low bp, you should know to increase levo and not dop."
I have to disagree with this one. Norepinephrine is naturally found catecholamine within the body with primary role as a neurotransmitter. It also acts on the sympathetic nervous system, along with epinephrine, during the body's fight or flight response and has positive chronotropic effect. As a drug, It acts primarily on alpha 1 & 2 receptors causing vasoconstriction but maintains some beta agonistic effects.
That being said, if I have a hypotensive & tachycardic patient on dopamine and norepi gtts, I would NOT increase the norepi as this would increase the tachycardia. Now high-dose dopamine has similar effects and not a good choice as a vasopressor. I would look for adding a Neo or vasopressin gtt. Increasing the tachycardia shortens diastole and reduces coronary filling time, reduces cardiac output, and increases the risk of cardiac ischemia. If you need blood pressure now, do what you have to do but for an entire shift I would look at other options.
