Minute Ventilation Calculator
Introduction & Importance
Minute ventilation (MV) is a crucial respiratory parameter that reflects the total amount of air moved into and out of the lungs per minute…
How to Use This Calculator
- Enter the tidal volume (TV) in milliliters (ml).
- Enter the respiratory rate (RR) in breaths per minute (bpm).
- Click ‘Calculate’.
Formula & Methodology
Minute ventilation is calculated using the formula: MV = TV × RR.
Real-World Examples
Case 1
A patient with a TV of 500 ml and an RR of 12 bpm has an MV of 6000 ml/min.
Case 2
A patient with a TV of 650 ml and an RR of 15 bpm has an MV of 9750 ml/min.
Case 3
A patient with a TV of 480 ml and an RR of 10 bpm has an MV of 4800 ml/min.
