Tachypnea is defined as:

Tachypnea refers to an abnormally rapid breathing rate, which is characterized by more than 20 breaths per minute. This condition can occur due to various factors such as fever, anxiety, or respiratory disorders, and is significant because it indicates that the body may be trying to increase oxygen intake or eliminate carbon dioxide more rapidly. The prevalence of a respiratory rate greater than 20 breaths per minute is clinically recognized as tachypnea in both adults and children. Understanding this definition is critical for healthcare professionals, as it helps in identifying respiratory distress or other underlying health issues promptly.
