Breathing is measured in breaths per minute or bpm. To get an accurate measurement, the person must be at rest. This means she is not breathing faster than usual due to exercising. She should be still for at least 10 minutes before you count her breaths.  Have the person sit up straight. If you are measuring an infant, lay the baby flat on her back on a firm surface. Use a stop watch to time one minute. Count the number of times the person's chest rises and falls during that minute. If you tell the person that you are going to measure her breathing, she is likely to change her breathing rate without realizing it. Tell her to breathe normally. To improve the accuracy of your result, you can take the measurement three times and average the answers. If you are pressed for time, count the breaths in a 15 second window, then multiply the number of breaths by 4. This gives a close approximation of breaths per minute and is useful in emergency situations. Children breathe faster than adults so you need to compare your number to the normal number of breaths per minute for the person's age group. The rates are as follows  30 to 60 bpm for an infant who is 0 to 6 months old 24 to 30 bpm for an infant who is 6 to 12 months old 20 to 30 bpm for a child who is 1 to 5 years old 12 to 20 for a child who is 6 to 11 years old 12 to 18 for someone who is 12 or older If someone's breathing rate is higher or lower than the expected range, and she has not been exercising, this could be an indication that something is wrong. Other signs of respiratory distress include:  Flaring the nostrils during each breath. The skin has a dusky color. The ribs and center of the chest are pulled in. The person makes a wheezing, grunting, or crying sound when breathing. The person's lips and/or eyelids are blue. The person is breathing with their entire shoulders/chest area. This is considered labored breathing. If you are with an individual and the breathing rate needs to be taken frequently, then try re-taking it every 15 minutes for non...
