🫁 Mechanical Power (Simplified VC)
UseWhen to use: ARDS / protective ventilation teaching when RR, VT, Ppeak, and PEEP are known.
StrataHigher MP is a VILI risk teaching cue — optimize VT, rate, and pressures; prefer Pplat-based forms when avail…
LimitsWhen not to use: major patient effort / nonlinear modes. · Pitfall: using Pplat as Ppeak interchangeably. · Thresholds are not absolute.

When to use
When to use: ARDS / protective ventilation teaching when RR, VT, Ppeak, and PEEP are known.
How it works
MP = 0.098 × RR × VT(L) × (Ppeak − ΔP/2); ΔP = Ppeak − PEEP.
Key points
- 0.098×RR×VT×(Ppeak−ΔP/2).
- J/min energy cue.
- Next: ΔP / Cstat.

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.
| Respiratory rate | 20 /min |
|---|---|
| Tidal volume | 420 mL |
| Peak inspiratory pressure | 28 cmH₂O |
| Total PEEP | 8 cmH₂O |

- ΔP (Ppeak−PEEP)：20.0 cmH₂O
- VE：8.40 L/min
- Cue：≈12–17 J/min — intermediate MP band

FAQ
Frequently asked questions
- Does Mechanical Power (Simplified VC) 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 Mechanical Power (Simplified VC) calculated in practice? Can you show a worked example?
- Inputs: Respiratory rate 20 /min, Tidal volume 420 mL, Peak inspiratory pressure 28 cmH₂O, Total PEEP 8 cmH₂O → Result: Mechanical power 14.8 J/min（ΔP (Ppeak−PEEP): 20.0 cmH₂O, VE: 8.40 L/min, Cue: ≈12–17 J/min — intermediate MP band）
