In post-resuscitation care, the role of Push Dose Epinephrine is to maintain what?

• A. To sedate the patient
• B. To maintain MAP > 65, SBP > 90
• C. To cause tachycardia
• D. To improve oxygenation

Answer: (B)

After resuscitation, the priority is to preserve brain and heart perfusion by keeping blood pressure at a level that ensures adequate organ blood flow. Push dose epinephrine provides rapid, controllable vasopressor support to raise and maintain blood pressure, aiming for a mean arterial pressure around 65 mmHg and a systolic pressure above 90 mmHg. It works quickly and its effects are short-acting, allowing careful titration while longer-term strategies are arranged. Mechanistically, epinephrine stimulates alpha-adrenergic receptors to constrict blood vessels and beta-adrenergic receptors to increase heart rate and contractility, together boosting systemic vascular resistance and cardiac output to improve perfusion. Sedation isn’t its purpose, tachycardia is a potential side effect rather than the goal, and oxygenation is primarily addressed through ventilation and gas management, with BP support helping ensure adequate tissue oxygen delivery.
