Background
Shock index (SI)[1]
SI = HR / SBP
- Used when HR and SBP do not predict severity of hypovolemia in early stages
- May be used as secondary triage tool in mass casualty incidents[2]
- 0.5-0.7 is normal
- >0.70-0.75 for occult shock or requirement of life-saving intervention
Simple Shock Index (sSI) was recently proposed. Subtracting SBP from HR is a good SI substitute. Working with integers is easier than dividing them, improving value availability.[3]
