What blood pressure parameter is targeted after ROSC?

What blood pressure parameter is targeted after ROSC?

• A. Maintain systolic BP ≥ 120
• B. Maintain MAP ≥ 80 mmHg
• C. Maintain diastolic BP ≥ 60
• D. Maintain MAP ≥ 65 mmHg

Answer: (D)

After ROSC, the priority is to ensure adequate perfusion to the brain and heart to prevent further injury. This is best assessed and targeted using mean arterial pressure (MAP) because MAP reflects the overall pressure driving blood flow through the organs over the entire cardiac cycle, not just a single part of the cycle like systole or diastole. Maintaining MAP around 65 mmHg provides a reasonable guarantee of sufficient cerebral and coronary perfusion, even if autoregulation is impaired after cardiac arrest. Therefore, the recommended target is MAP ≥ 65 mmHg. Higher targets are not routinely required unless there are specific concerns about cerebral perfusion or other conditions, and focusing on systolic or diastolic values alone can misrepresent overall perfusion.
