Shock index: Difference between revisions

Revision as of 14:59, 20 June 2021

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].
