If tidal volume is 0.5 L and respiratory rate is 12 breaths per minute, what is the minute ventilation in mL/min?

Minute ventilation is the total air moving in and out of the lungs per minute. It’s calculated by multiplying the amount of air per breath (tidal volume) by how many breaths you take each minute (respiratory rate). Here, tidal volume is 0.5 L, which is 500 mL per breath, and the rate is 12 breaths/min. Multiply: 500 mL × 12 = 6,000 mL/min, or 6 L/min. So the minute ventilation is 6,000 mL/min.
