Respiration rate for adults and children
Respiration Rate is the number of respiratory cycles a person completes in one minute. A typical healthy adult has a respiration rate of 15 to 20 per minute, measured by counting each inhalation or each exhalation (a respiratory cycle is one of each). Respiration rate normally is lower at rest and during sleep, and accelerates as well as intensifies with physical activity and exercise. Children have higher respiration rates than adults. The respiration rate typically increases with health circumstances such as INFECTION, FEVER, trauma, PAIN, and strong emotions such as fear. The brainstem regulates the respiration rate, in intimate coordination with other vital functions such as HEART RATE and BLOOD PRESSURE. The respiration rate remains at roughly a ratio of 1 to 4 with the heart rate (one breath for every four contractions of the HEART).
