How much air is breathed by a normal, healthy person in 24 hours?
Added by Dawn M.
Step 1
First, we need to know the average breathing rate of a healthy person. According to the American Lung Association, the average adult at rest takes 12 to 20 breaths per minute. Let's take the lower end of that range and assume 12 breaths per minute. Show more…

The average breath takes in about $1 \frac{1}{2}$ pints of air. The air is about $20 \%$ oxygen. Of the oxygen that we breathe, about $25 \%$ makes its way into our bloodstream. How much oxygen does the average person take in every day? (See Exercise 112 .)
