During most daily activities, the human respiration rate is most closely linked to the blood levels of carbon dioxide.
The normal rate of respiration for healthy adults is between 12–20 breaths per minute. At this respiration rate, the carbon dioxide exits the lungs at identical rate that the body produces it.
In order to measure your respiration rate firstly sit down and relax than measure the number of times your chest rises over a period of 1 minute and record this number. Carbon dioxide level in blood indicates how many millimoles of carbon dioxide is in a liter of blood.
