What is the appropriate dosage of Epinephrine for cardiac arrest?

The appropriate dosage of Epinephrine for cardiac arrest is 1mg every 3-5 minutes. This recommendation is based on established guidelines for advanced cardiac life support (ACLS). Epinephrine acts as a potent vasoconstrictor that increases systemic vascular resistance and improves coronary and cerebral perfusion pressures during cardiopulmonary resuscitation (CPR). Administering 1mg every 3-5 minutes is crucial as it ensures that the medication is effective in stimulating the heart and enhancing the likelihood of return of spontaneous circulation (ROSC) without excessive dosing that could lead to adverse effects. This dosage provides the optimal chance for resuscitation efforts to succeed while retaining adherence to current procedural standards in emergency medicine.
