💓 Diastolic Shock Index (DSI)

UseWhen to use: septic/vasodilatory shock bedside severity cues with arterial diastolic tone.

Loading calculator…

StrataBands around <1.5 / 1.5–2 / >2 discussed for rising risk; integrate MAP/lactate.

LimitsWhen not to use: pure cardiogenic shock without vasodilation context. · Pitfall: inaccurate noninvasive DBP. · Not a sole pressor protocol.

When to use

When to use: septic/vasodilatory shock bedside severity cues with arterial diastolic tone.

How it works

DSI = heart rate / diastolic blood pressure.

Key points

  • HR/DBP ratio.
  • Cut cues 1.5 and 2.
  • Next: perfusion + vasopressor review.

Worked calculation

The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.

Heart rate110 /min
Diastolic BP50 mmHg

→DSI2.20

  • HR / DBP：110 / 50
  • Cue：>2 — higher mortality association in vasodilatory/septic shock cohorts

FAQ

Frequently asked questions

Does Diastolic Shock Index (DSI) upload patient data? Where is it calculated?
Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
How is Diastolic Shock Index (DSI) calculated in practice? Can you show a worked example?
Inputs: Heart rate 110 /min, Diastolic BP 50 mmHg → Result: DSI 2.20（HR / DBP: 110 / 50, Cue: >2 — higher mortality association in vasodilatory/septic shock cohorts）
