What is Shock Index?

Shock Index: - An early bedside assessment - to quickly identify septic/ dengue patients early for resuscitation - Is HR divided by SBP - Normal range: 0.5 - 0.7 - SI > 1.0 is a/w significant poor clinical outcome with acute respiratory failure - SI value is inversely proportionate with CI, SV, & MAP. - SI value in most cases raise in proportionate with lactate. How this two correlates? - Shock state (as a response of HR > SBP) causes cellular hypoxia, increase in norepinephrine release, resulting anaerobic respiration      - increase in lactate production!
