Shock Index
SHOCK INDEX (SI) = Heart Rate / Systolic Blood Pressure
Application
SI can be used to identify patients needing a higher level of care despite vital signs that may not appear strikingly abnormal. This index is a sensitive indicator of left ventricular dysfunction and can become elevated following a reduction in left ventricular stroke work.
Interpretation
- Normal SI = 0.5 to 0.7
- If SI > 0.9 was helpful to identify patients in the ED requiring admission and/or intensive care despite apparently stable vital signs
- Persistent high SI has been associated with poor outcome
The answer to the above clinical scenario: By applying the above equation, (110/100 = 1.1), this patient has a high shock index and requires a high level of care.
