What MAP should be maintained in the emergent phase?

• A. 60 mmHg
• B. 70 mmHg
• C. 80 mmHg
• D. 90 mmHg

Answer: (B)

In the emergent phase, the priority is ensuring adequate tissue perfusion as the body is vulnerable to hypovolemia from fluid shifts. MAP is the best single indicator of whether organs are being perfused, so the target is set to keep MAP around 70 mmHg. This level provides sufficient perfusion to vital organs like the brain and kidneys without pushing fluids to excessive levels that can worsen edema. A MAP near 60 would risk organ ischemia, while aiming for 80–90 tends to require more aggressive fluids and increases the chances of fluid overload and edema. Therefore, 70 mmHg is the best balance to maintain during this phase.
