Methodology
Minute ventilation
VE = Vt × RR
Total gas moved in and out of the lungs each minute.
- Who it is for
- Adults, spontaneous or mechanical ventilation.
- Version
- 1.0.0
Worked example: how to calculate minute ventilation
Inputs
- Tidal volume
- 450 mL
- Respiratory rate
- 14 breaths/min
Result
- Minute ventilation
- 6.3 L/min
Calculation:
450 × 14 / 1000 = 6.3
An illustration with sample values, worked out with the same method the tool above uses.
Limitations
- Includes dead-space ventilation; alveolar ventilation is lower.
