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].

Additional studies have been done[3].
