If the volume of the anatomical dead space volume is about 150 mL, how much fresh air entered the alveoli during each breath when the volunteer was at rest?
About 300-400 mL
The fresh air that enters the alveoli during each breath is equal to the tidal volume (TV) minus the anatomical dead space (ADS).
Therefore, if the anatomical dead space volume is about 150 mL, we need to subtract that volume from the tidal volume to find out how much fresh air entered the alveoli during each breath at rest.
Assuming a typical resting tidal volume of around 500 mL, the amount of fresh air that enters the alveoli during each breath can be calculated by:
Fresh air volume = Tidal volume – Anatomical dead space volume
Fresh air volume = 500 mL – 150 mL
Fresh air volume = 350 mL
Therefore, approximately 350 mL of fresh air enters the alveoli during each breath at rest, assuming an anatomical dead space volume of 150 mL.
