In Cardiac Arrest Asystole/PEA, what is the drip configuration for the drug given?

• A. Epinephrine: 2 mg in 100 mL bag, 10 drop set, 1 drop/sec
• B. Epinephrine: 1 mg in 100 mL bag, 10 drop set
• C. Amiodarone: 150 mg in 100 mL bag
• D. Lidocaine: 1 mg/kg in 100 mL bag

Answer: (A)

When the heart isn’t pumping effectively in arrest (asystole or PEA), epinephrine is given as a continuous infusion to boost perfusion pressure and improve blood flow to the heart and brain during CPR. The chosen setup—epinephrine 2 mg in 100 mL, using a 10 drops per mL drip set, at a rate of 1 drop per second—creates a steady, controllable infusion rather than repeated boluses. With this configuration, the flow rate is about 6 mL per minute (1 drop/sec with a 10 gtt/mL set equals 60 drops/min ÷ 10 gtt/mL = 6 mL/min). The resulting dose is roughly 0.12 mg per minute (2 mg/100 mL × 6 mL/min = 0.12 mg/min), which translates to about 1–2 micrograms per kilogram per minute for a typical adult. This rate provides sustained sympathetic stimulation to support coronary and cerebral perfusion during ongoing CPR, aligning with guidelines that favor continuous infusion after initial boluses in non-shockable rhythms. Other options either describe different drugs, different dosing methods, or rely on bolus administration rather than a continuous infusion, which is not ideal for maintaining perfusion during prolonged resuscitation.
