This will vary widely and will depend on several things including age, fitness, activity level and health issues. It also depends on whether you are talking about resting respiration or respiration during exercise.
the answer is 20
Respirations per minute.
The respiration rate is the number of breaths taken in 1 minute.
Respirations, or breaths, are measured by how many occur in one minute. Many medical people count breaths for 15 seconds, then multiply that number by 4 (equaling one minute's worth)
The normal breathing rate for an infant is about 30-60 breaths per minute. This number goes down as the infant ages.
Respiration rate is the number of breaths in a minute. If you hold your breath for a minute the respiratory rate will be zero so yes
12–20 breaths per minute (12, if it had to be one number)
The average respiratory rate for adults is 10 to 14 breaths per minute. Taking this average, the number of breaths in an hour would be 600 to 840 per hour.
Average respiratory rate reported in a healthy adult at rest is usually given as 12 breaths per minute (12⁄60 Hz)[1][2] but estimates do vary between sources, e.g., 12-20 breaths per minute, 10-14,[3] between 16-18,[4] etc. With such a slow rate, more accurate readings are obtained by counting the number of breaths over a full minute.
The rate of respiration is the number of breaths per minute. All you have to do is count either the number of breaths in OR out (not both) in one minute. To get more reliable results, the experiment should be repeated several times.
Number of beats per minute the heart drops after exercise.
