MAP target ≥ 65. Sepsis surviving guidelines, vasopressor titration, post-cardiac- arrest care — all target MAP at or above 65 mmHg. Below 65 is underperfusion territory; chronic hypertensives may need higher targets (75 - 85 mmHg) to maintain organ perfusion they're used to.
Shock index catches occult shock. A shock index ≥ 1.0 (heart rate equal to or higher than systolic BP) is associated with worse outcomes and often appears BEFORE the systolic frankly drops. It's an early marker that's easy to miss if you're only watching BP. Modified shock index (≥ 1.3) and age shock index are further refinements used in trauma triage.

About MAP + Shock Index

Mean arterial pressure + shock index from BP and HR. Surfaces perfusion-target status (MAP ≥ 65) and shock-index thresholds (≥ 1.0 concerning).
