Clinical takeaway

Useful in trauma, sepsis and obstetric haemorrhage.

When to use

Identify compensated shock when HR and BP look individually acceptable.

How it works

Shock index = heart rate ÷ systolic BP. Normal 0.5–0.7; ≥ 1.0 suggests significant compromise.

Key points

  • Useful in trauma, sepsis and obstetric haemorrhage.
  • Modified shock index (HR/MAP) and age-adjusted forms exist.
  • Trends matter as much as a single value.
