Definition of Respiration Rate

respiration rateThe number of respiratory cycles a person completes in one minute. A typical healthy adult has a rate of 15 to 20 per minute, measured by counting each inhalation or each exhalation (a respiratory cycle is one of each).

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 INFECTIONFEVER, trauma, pain, and strong emotions such as fear.

The brainstem regulates the respiration rate, in intimate coordination with other vital functions such as HEART RATEand 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).
