What is the recommended adult dosage of Epinephrine for cardiac arrest?

The recommended adult dosage of Epinephrine for cardiac arrest is indeed 1 mg administered intravenously (IV) or intraosseously (IO) every 3 to 5 minutes during resuscitation efforts. This dosage is consistent with guidelines from resuscitation councils and reflects the need for immediate and effective support of cardiac function in an arrest situation.

Epinephrine works by stimulating alpha and beta-adrenergic receptors, which leads to increased heart rate, improved myocardial contractility, and peripheral vasoconstriction. These effects enhance blood flow to the heart and brain during cardiopulmonary resuscitation (CPR), making it crucial for increasing the chances of successful resuscitation.

The administration interval of every 3 to 5 minutes allows for a consistent and effective level of medication in the body, aligning with comprehensive advanced cardiac life support (ACLS) protocols. This timing is essential to ensure that the heart has a chance to respond to the medication effectively while maintaining pressure during critical moments of CPR.
