Dr. Feng Tao
A healthy adult typically breathes about 18 times per minute. However, because newborns’ respiratory systems are not yet fully developed, their respiratory rate is higher—often reaching 30–35 breaths per minute. Additionally, respiratory rate may vary due to emotional states or physical activity. A rate below the normal range indicates bradypnea (abnormally slow breathing), whereas a rate above the normal range suggests tachypnea (abnormally rapid breathing).
