Answer:
Option C
Explanation:
Option
A. 6440 mL/min
B. 4340 mL
C. 3500 mL/min
D. 2940 mL/min
Solution
It is required to find the minute ventilation which is equal to the product of rate of breathing and the total amount of gas being inhaled or exhaled per breathe. Let this minute ventilation be denoted by ""
Thus,
where TD is the tidal volume and Br is the rate of breathing
Substituting the given values we get
We will now reduce the air held in the conducting zone of respiratory system
Air held per breathe
Total Air held
Amount of fresh air one can breathe in and out every minute
Hence, Option C is correct
