Question

What is the minute ventilation of an average adult male at rest breathing at a rate of 10 breaths per minute?

A) 5000 milliliters per minute
B) 36,000 milliliters per minute
C) 48,000 milliliters per minute
D) 60,000 milliliters per minute

Answer 1

The minute ventilation of an average adult male at rest with a breathing rate of 10 breaths per minute is 5000 milliliters per minute.

Step-by-step explanation:

Calculating Minute Ventilation:

The minute ventilation is defined as the volume of air breathed in and out by an individual in one minute. For an average adult male at rest, the typical tidal volume— or the volume of air inhaled during a normal breath— is approximately 500 milliliters (mL). Given a respiratory rate of 10 breaths per minute, we can calculate the minute ventilation as follows:

Minute Ventilation = Tidal Volume x Respiratory Rate

Minute Ventilation = 500 mL/breath x 10 breaths/minute

Therefore, the minute ventilation = 5000 milliliters per minute (A).

This is the amount of air moved in and out of the lungs per minute under resting conditions.
