Rapid Vent Calculator

Rapid Vent Calculator

About this app

Rapid Vent Calculator is a clinician-focused field guide and reference tool for adult ventilator setting calculations, RSI medication dosing, and quick respiratory care references.

Designed for paramedics, EMS clinicians, respiratory therapists, nurses, physicians, transport teams, ER teams, ICU clinicians, and hospital-based critical care providers, Rapid Vent Calculator helps organize common ventilator and airway calculations into a fast, practical workflow.

Enter patient sex, height, weight, selected mL/kg, and metabolic acidosis status to generate adult starting-point ventilator values, including respiratory rate, tidal volume, and minute ventilation. Calculations use ideal body weight and lung-protective ventilation principles for adult ventilator management.

Rapid Vent Calculator also includes RSI medication dosing estimates, normal ventilator values, ABG/VBG blood gas reference charts, RASS reference guidance, dark and light mode, recent session resume, and shareable result snapshots.

Whether used by EMS in the field, paramedics during transport, nurses and respiratory therapists in the ER, physicians in the hospital, or ICU clinicians managing ventilators, the Rapid Vent Calculator is built to keep key adult ventilation references organized and easy to access.

Rapid Vent Calculator is intended as a clinical reference and calculation aid for licensed healthcare professionals caring for adult patients. It is not a protocol, diagnosis tool, treatment directive, or substitute for clinical judgment. All values are starting-point estimates and must be verified against the patient’s condition, local protocols, institutional policy, and clinician's scope of practice.

Ratings and reviews

The app is great for quick reference for when setting up your ventilator. Also does all of your drug calculations for you. One app does all your required calculations. If you are in emergency medicine, respiratory therapy, etc, I highly recommend!

Great app, 2 suggestions... 1. add the ability to do just inches for those of us who will use a tape measure and get like 78 inches... 2. let the app calculate ideal body weight based on patient height.

Follow your local protocols, but this is a good quick reference

What’s new

• I:E ratio now shown by clinical context: 1:2 to 1:3 for normal lung mechanics, 1:4 or more for asthma/COPD exacerbation, with sources
• PEEP, FiO₂, SpO₂, and SaO₂ reference values updated to published, cited sources
• COPD-specific SpO₂ row removed; follow your local protocol
• Number fields no longer clear when a digit is mistyped
• Smoother scrolling on older devices and reliability improvements
