Divide heart rate by systolic blood pressure for the shock index.
| Shock index | – |
Use this calculator for shock index = heart rate ÷ systolic mmHg. A round “look again” sketch is often around 0.9 in adults; pregnancy and beta-blockers change the reading. MEWS and NEWS add more vitals; they are not cloned here. This is not a diagnosis of shock.
Heart rate: Beats per minute.
Systolic: Systolic blood pressure, mmHg.
Shock index: Heart rate over systolic.
