Which term refers to an abnormal increase in the breathing rate of a patient?

The term that refers to an abnormal increase in the breathing rate of a patient is tachypnea. This condition is specifically characterized by a respiratory rate that is higher than normal, indicating that the body may be experiencing some physiological stress or underlying medical issues that require faster breathing to meet oxygen demands or expel carbon dioxide.

Tachypnea can occur in various situations, such as during exercise, in response to anxiety, or due to respiratory or cardiovascular conditions. It's important for healthcare providers to recognize tachypnea, as it can be a sign of serious health concerns that may require immediate attention.

Bradypnea, in contrast, refers to a slower than normal breathing rate, which is not relevant to this question. Apnea describes a temporary cessation of breathing, while dyspnea pertains to the subjective experience of difficulty in breathing. Understanding these definitions helps clarify why tachypnea is the correct term for an increased breathing rate.
