For school-age children, what defines bradypnea?

Bradypnea in school-age children is defined as a respiratory rate that is lower than what is considered normal for that age group. The typical respiratory rate for school-age children ranges from about 18 to 30 breaths per minute. Therefore, a rate of less than 18 breaths per minute indicates bradypnea.

Choosing a threshold less than 16, 20, or 22 breaths per minute may incorrectly classify a child who is just on the lower end of normal. By setting the cutoff at less than 18 breaths per minute, it accurately identifies those children who are experiencing below-normal respiratory rates, which is essential for timely recognition and intervention in potential respiratory distress or failure. Recognizing bradypnea is crucial for clinicians in managing children's health effectively.
