What is the concentration used for push-dose epinephrine in ROSC?

• A. 1:10,000
• B. 1:1000
• C. 1:20,000
• D. 1:2000

Answer: (A)

Push-dose epinephrine in ROSC is given using a dilute, easily titratable solution so you can raise perfusion pressure with small, repeatable boluses. The standard concentration chosen is 1:10,000, which gives 0.1 mg of epinephrine per milliliter. With typical push doses of about 0.5 to 1 mL, each bolus delivers roughly 50–100 micrograms, allowing quick dose adjustments based on the patient’s blood pressure and perfusion response. This approach provides a fast, controllable vasopressor effect to improve coronary and cerebral perfusion during CPR and early ROSC. Other concentrations would deliver far more or far less drug per dose, making titration unreliable and increasing risks like tachyarrhythmias or inadequate perfusion, which is why 1:10,000 is used.
