What is the epinephrine dosage in PEA?

• A. 1 mg every 3 to 5 minutes
• B. 1 mg every 1 to 2 minutes
• C. 0.5 mg every 3 to 5 minutes
• D. 2 mg every 3 to 5 minutes

Answer: (A)

In PEA, epinephrine is used to improve perfusion during CPR by causing vasoconstriction that raises coronary and cerebral perfusion pressures. The best dose is 1 mg given IV or IO every 3 to 5 minutes during CPR, repeated at that interval until return of spontaneous circulation or termination of resuscitation. This schedule strikes a balance between providing vasopressor support and allowing ongoing chest compressions to continue. Doses like 0.5 mg every 3 to 5 minutes or 2 mg every 3 to 5 minutes aren’t the recommended practice for PEA, and giving 1 mg every 1 to 2 minutes would be more frequent than guidelines suggest and isn’t supported by evidence for this scenario.
