Formula Used
- Set Minute Ventilation = Respiratory Rate × Set Tidal Volume ÷ 1000
- Exhaled Minute Ventilation = Respiratory Rate × Exhaled Tidal Volume ÷ 1000
- Cycle Time = 60 ÷ Respiratory Rate
- Expiratory Time = Cycle Time − Inspiratory Time
- I:E Ratio = 1 : (Expiratory Time ÷ Inspiratory Time)
- Driving Pressure = Plateau Pressure − PEEP
- Resistive Pressure Component = Peak Inspiratory Pressure − Plateau Pressure
- Static Compliance = Set Tidal Volume ÷ (Plateau Pressure − PEEP)
- Dynamic Compliance = Set Tidal Volume ÷ (Peak Inspiratory Pressure − PEEP)
- Total PEEP = Entered PEEP + Entered Auto-PEEP
- Estimated Leak (%) = (Set Tidal Volume − Exhaled Tidal Volume) ÷ Set Tidal Volume × 100

How to Use This Calculator
- Enter the currently observed ventilator mode and clinician-selected values from the ventilator screen.
- Add measured pressures and optional values such as exhaled tidal volume, SpO2, PaCO2, and notes.
- Press Calculate Review Metrics to display derived values above the form.
- Review the summary cards, the detailed table, and the Plotly pressure graph.
- Use the CSV or PDF buttons to save the review output for simulation, teaching, or internal documentation.
- Do not use this page to generate or titrate patient-care settings. It does not recommend treatment.
FAQs
1) Does this worksheet choose ventilator settings?
No. It only computes review metrics from values already entered by a clinician or instructor. It is designed for documentation, simulation, and education rather than patient-care decision support.
2) What is driving pressure here?
Driving pressure is calculated as plateau pressure minus PEEP. This page reports the arithmetic result only and does not judge whether the value is clinically acceptable for a specific patient.
3) Why are static and dynamic compliance both shown?
They describe different relationships using entered pressures. Static compliance uses plateau pressure, while dynamic compliance uses peak pressure. Seeing both helps compare elastic and resistive contributions during review.
4) What happens if exhaled tidal volume is missing?
The worksheet still calculates other values. Exhaled minute ventilation and leak percentage remain blank until an exhaled tidal volume is entered.
5) Can I use this page for adult, pediatric, or neonatal care?
This template is generic and educational. It does not contain age-specific recommendations, protocols, alarms, or safety limits. Any real patient use requires qualified clinical oversight and appropriate device-specific guidance.
6) Why must inspiratory time be less than cycle time?
Cycle time is the total time available for one breath at the entered respiratory rate. Inspiratory time must fit within that cycle or the timing math becomes invalid.
7) What does the leak percentage estimate show?
It compares set and exhaled tidal volume when both are entered. The result is a simple estimate for review and should not replace circuit checks, waveform analysis, or device alarms.
8) Can I export the calculated output?
Yes. The page includes CSV and PDF download buttons after calculation. They export the result table for training files, simulation notes, or internal handoff documents.
