What is the target SBP to maintain with push-dose pressors in shock?

• A. SBP > 100
• B. SBP > 80
• C. SBP > 70
• D. SBP > 90

Answer: (D)

Maintaining arterial perfusion requires keeping the systolic blood pressure above a level that ensures organs, especially the brain and heart, receive enough blood flow. In shock, using push-dose pressors is a short-term bridge to restore and sustain perfusion while definitive treatment is arranged. The practical target is SBP above 90 mmHg, which provides enough perfusion pressure to reduce the risk of cerebral and cardiac hypoperfusion without driving excessive vasoconstriction or afterload. Lower thresholds (like 70–80) risk organ hypoperfusion, while aiming for a higher threshold (like 100) isn’t necessary unless patient-specific factors demand it.
