Breathing Rate × Tidal Volume Calculator
❤️ The human body. Use the Breathing rate × tidal volume formula to find ventilation, breaths per minute, tidal volume: pick the value you want, type the others, and the answer updates as you go.
Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.
What each letter means
| Quantity | Unit |
|---|---|
| Ventilation | L/min |
| Breaths per minute | /min |
| Tidal volume | L |
Worked example
Find the ventilation when Breaths per minute = 12 /min, Tidal volume = 0.5 L.
Using ventilation = breathing rate × tidal volume: Ventilation = 6 L/min.
Frequently asked questions
What is the formula for Breathing rate × tidal volume?
ventilation = breathing rate × tidal volume.
What do the letters stand for, and what units are used?
Ventilation in L/min, Breaths per minute in /min, Tidal volume in L.
How do you calculate ventilation?
Put the values into ventilation = breathing rate × tidal volume. For example, with Breaths per minute = 12 /min, Tidal volume = 0.5 L, ventilation = 6 L/min.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (ventilation, breaths per minute, tidal volume) and fill in the others: it rearranges the formula for you.
