What is the clinical term for an abnormally high respiratory rate?

The clinical term for an abnormally high respiratory rate is tachypnea. This condition is characterized by rapid breathing, where the respiratory rate exceeds the normal range for a resting state, typically defined as over 20 breaths per minute in adults. Tachypnea can indicate various underlying issues, such as anxiety, fever, respiratory disorders, or metabolic conditions, where the body may require more oxygen or attempt to expel excess carbon dioxide.

In contrast, the other terms have different implications. Bradypnea refers to an abnormally slow respiratory rate, suggesting a rate below the normal threshold. Dyspnea describes the sensation of difficult or labored breathing, which may occur regardless of the respiratory rate. Apnea signifies a temporary cessation of breathing, which can be a critical condition requiring immediate intervention. Thus, understanding these terms is essential for accurate clinical assessment and response to patients' respiratory needs.
