Respiratory rate is the number of breaths per minute, controlled by the brain's respiratory center and varying with age. Alveolar ventilation is maintained by adjusting respiratory rate and tidal volume.
Respiratory rate is the number of breaths taken per minute and can indicate disease conditions. It is controlled by the respiratory center in the brain, responding to blood levels of carbon dioxide, oxygen, and pH.
The normal respiratory rate for children changes as they grow. For children under 1 year, it is 30-60 breaths/min, while for adolescents and adults, it ranges from 12-18 breaths/min.
Alveolar ventilation is maintained by adjusting the respiratory rate and tidal volume to meet oxygen demand while preventing carbon dioxide buildup.
