How much adrenaline should be given in non-shockable rhythms?

In the context of resuscitation protocols for non-shockable rhythms such as asystole or pulseless electrical activity (PEA), the recommended dose of adrenaline (also known as epinephrine) is indeed 1mg. This administration is crucial because adrenaline functions to enhance coronary perfusion pressure during cardiopulmonary resuscitation (CPR), facilitating improved blood flow to the heart and potentially increasing the chances of return of spontaneous circulation (ROSC).

In cases of non-shockable rhythms, adrenaline is typically given every 3-5 minutes during the resuscitation attempt, and the 1mg dosage aligns with established advanced cardiovascular life support (ACLS) guidelines. This dosage is effective in stimulating alpha-adrenergic receptors, which leads to vasoconstriction and improved perfusion pressure, and beta-adrenergic receptors, which can enhance heart function if it starts to regain activity.

Understanding the correct dosage is critical for health care providers in emergencies, as the effectiveness of resuscitation can hinge on timely and appropriate medication administration. In this case, 1mg stands as the standard that practitioners rely on, reinforcing its importance in high-pressure situations.
