Question

3. Lets see if you understand the Q10 rule. A surgeon has placed you in an ice bath in preparation for thoracic (chest) surgery. Your body is chilled to 10 °C and your respiration rate (breathing rate) is only 1.5 breaths/minute. According to the Q10 rule, what is your predicted breathing rate when, after surgery, your body temperature is re-warmed to normal values of 38-39 °C? A. 3 breaths/minute. B. 38-39 breaths/minute. C. 24.5 breaths/minute. D. approximately 12 breaths/minute E. 6 breaths/minute.

Explanation / Answer

Answer: Option D is correct.

Explanation:

According to Q10 rule, the experimental quantity (breaths per minute) doubles for every 10'C temperature increase.

Initial temperature = 10 'C

Final temperature = 39'C

Number of Q10 = ~3

Inital breath rate = 1.5 breaths per minute

Final breath rate = 1.5 X 2 X 2 X 2 = ~12 breaths per minute
