The shock index (SI) is the heart rate (HR) divided by systolic blood pressure (SBP) .
The pretransport shock index can predict the need for resuscitation in the hospital[1].
Other variations are[2]:
- Shock index (SI) is the heart rate / systolic blood pressure (SBP). The normal range is 0.5–0.7
- Modified Shock Index (MSI) is the heart rate / mean arterial pressure (MAP)
- Age Shock Index (age SI) is SI * age.
Of these three measures, for GI bleeding, Age SI may better prognosticate[2].
In the ProCESS randomized controlled trial, titrating to a shock index of < 0.8 after mini-boluses of fluids, had similar mortality to other methods of monitoring fluids[3].
Additional studies have been done[4].
