What is the recommended epinephrine dosing for cardiac arrest?

For cardiac arrest, the recommended dosing for epinephrine is 1 mg administered every 3 to 5 minutes during resuscitation efforts. This dosing guideline is designed to optimize the chances of restoring spontaneous circulation while minimizing potential side effects from excessive doses.

Epinephrine works by increasing coronary and cerebral perfusion pressure during cardiopulmonary resuscitation (CPR), helping to improve the chances of successful defibrillation and overall survival. Administering it every 3 to 5 minutes ensures that there is a consistent catecholamine effect without overwhelming the system, which could happen with higher doses or more frequent dosing.

The other options provided do not align with the current resuscitation guidelines. Dosing too low or too high or at inappropriate intervals can hamper the effectiveness of resuscitation efforts or lead to complications. Thus, adhering to the recommended 1 mg every 3 to 5 minutes is critical in managing cardiac arrest situations effectively.
