What condition is characterized by a respiratory rate exceeding 25 breaths per minute?

The condition characterized by a respiratory rate exceeding 25 breaths per minute is known as tachypnea. This term specifically refers to an increased respiratory rate, which can occur in various situations, such as during exercise, anxiety, or respiratory distress. It is an important clinical sign as it may indicate underlying health issues, particularly involving the respiratory or cardiovascular systems.

In contrast, apnea refers to a temporary cessation of breathing, hypopnea involves unusually shallow or slow breathing, and dyspnea describes the sensation of shortness of breath or difficulty in breathing. Understanding these concepts is crucial for identifying and addressing respiratory conditions effectively.
