🌬️ Driving Pressure (ΔP)
UseWhen to use: volume-controlled ventilation with reliable plateau pressure.
StrataHigher ΔP (especially >15) associates with mortality in ARDS analyses.
LimitsWhen not to use: without an adequate inspiratory hold / with strong e… · Pitfall: using peak pressure instead of plateau. · Not a solo VT prescription.

When to use
When to use: volume-controlled ventilation with reliable plateau pressure.
How it works
ΔP = Pplat − PEEP.
Key points
- Pplat−PEEP.
- >15 cue.
- Next: optimize VT/PEEP.

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.
| Plateau pressure (Pplat) | 24 cmH₂O |
|---|---|
| PEEP | 10 cmH₂O |

FAQ
Frequently asked questions
- Does Driving Pressure (ΔP) 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 Driving Pressure (ΔP) calculated in practice? Can you show a worked example?
- Inputs: Plateau pressure (Pplat) 24 cmH₂O, PEEP 10 cmH₂O → Result: ΔP 14.0 cmH₂O（Cue: 13–15 — intermediate; optimize VT/PEEP）
