3) Suppose you suffered a rib injury that inhibited your ability to take regular breaths due to the pain. If you needed to maintain the same minute volume as you calculated in this activity and your tidal volume was 0.2 L due to the injury, what would your respiratory rate have to be

22 breathes per minute

Explanation:

Respiratory rate:

It is the amount of breaths consumed per minute. The usual respiration rate for an adult that is not actively involved in any work is 12 to 20 breaths per minute. A respiration rate that is below 12 or above 25 breaths per minute while not actively involved in any work is considered abnormal.

MV = TV * (breaths/minute)

4.4 = 2 * B/M

B/M=4.4/2

Therefore,

In our question, Respiratory rate is equivalent to 22 breathes per minute
