Other than the person in the monitor role, Who can assist with interpreting the arrest rhythm
code leader
build up of plaque in the vessel walls leading to narrowing or occlusion
atherosclerosis
neurotransmitter of the parasympathetic system and the enzyme that breaks it down

Injury from hypothermia may result in this on an EKG

Using the lowest dose of levophed, calculate the gtts/min on a 60 gtt set for a 80 kg patient. Available to you is a 1L bag of saline and 4mg of Levophed.

A patient has received 1 defibrillation, 1 dose of epinephrine 1mg, a second defibrillation, and 300mg of Amiodarone. The patient on next rhythm check has a slow weak carotid and sinus bradycardia on the monitor. The next step is to?
Continue ventilations at 1 breath q 6 seconds, obtain a 12 lead and blood pressure.
General weakness, radiating pain to jaw and left arm, shortness of breath
Common signs in conjunction with anginal pain associated with myocardial ischemia

Left main coronary artery
