What is the typical dosage of epinephrine for cardiac arrest?

The typical dosage of epinephrine for cardiac arrest is 1 mg administered intravenously (IV) or intraosseously (IO) every 3 to 5 minutes during resuscitation efforts. This dosage is based on current advanced cardiac life support (ACLS) guidelines, which outline the standardized approach to managing cardiac arrest in emergency situations.

Epinephrine is a critical medication used in cardiac arrest because it acts as a powerful vasoconstrictor, helping to improve coronary and cerebral perfusion pressure during cardiopulmonary resuscitation (CPR). This increased blood flow can significantly enhance the chances of successful resuscitation and restore a perfusing rhythm.

While other dosages may exist in different contexts for various conditions, the established protocol for cardiac arrest specifically calls for 1 mg, making it the appropriate choice in this scenario.
