Please assume that the normal respiratory rate for an adult is 12 to 20 breaths per minute (BPM). If you encounter an adult patient who is breathing in 500ml of air in one breath and is breathing at a rate of 13 breaths
per minute, how many ml of air does the patient take in during one minute?
ml.

The correct answer is - 6500 ml.

Explanation:

The amount of air breathed in with each normal breath is known as tidal volume (TV). The average tidal volume is 0.5 liters (500 ml) with each breath. The total volume of air that gets in the lungs in a minute is called minute ventilation (VE). The average minute ventilation is 6 liters per minute as a normal respiratory rate for an adult is 12.

In this case,

breathing in 500ml of air in one breath

breathing in 500ml of air in one breath

then, The minute ventilation is therefore

500 ml/breath X 13breaths / minute

= 6500 ml of air per minute.
