Question

What is the breathing rate in a man?

Answer 1

The rate at which breathing takes place is known as respiratory rate or breathing rate. Breathing rate is analyzed in breaths per minute and this is set and maintained by the respiratory center. The breathing rate in humans is taken by counting the number of breaths that occurred in one minute or by counting the number of times the chest rises.

Complete answer:
The normal breathing rate for a healthy human during rest is 12–18 breaths in one minute. A breathing rate that is less than 12 or above 25 breaths per minute which are measured during resting is considered an abnormal rate.
Using a fiber-optic breath rate sensor or by a magnetic resonance imaging scan, the breath rate can be measured. During fever, illness, or other abnormal health conditions the respiration rates tend to increase. 30-60 breaths per minute are the average respiratory rate of a newborn baby. When the is about six months of age the breathing rates drop, till which it continues to be a high rate. When the kids are school-aged they have normal respiration rates. When human beings get involved in various physical activities such as work out, the breathing rate becomes 35-45 breaths per minute, some hardcore athletes have a respiration rate of 60-70 per minute. During old age, the respiration becomes more shallow as the body demands more oxygen.

Note: -Activities like crying, sleeping, and aging can significantly influence the breathing rate.
-Pneumography and capnography are two different methods to measure the breathing rate of patients in critical stages.
-The respiratory rhythm that the body follows is 2 seconds for taking in oxygen and 3 seconds letting out carbon dioxide which makes the lower average rate of 12 breaths in a minute.
