tachypnea

Full Definition

Tachypnea refers to an elevated respiratory rate above normal ranges for age. In newborns, tachypnea is defined as a respiratory rate greater than 60 breaths per minute, while in older infants and children, the threshold varies by age. It can be a sign of respiratory conditions such as pneumonia, asthma, or bronchiolitis, or may indicate metabolic acidosis, fever, or cardiac conditions. Healthcare providers must interpret tachypnea in the context of the child's overall clinical presentation and age-appropriate vital sign ranges.
