What defines tachypnea?

Tachypnea is defined as an increased respiratory rate, typically above the normal range for a given age. In adults, a respiratory rate greater than 20 breaths per minute is generally considered tachypnea. This condition can be a physiological response to various stimuli such as exertion, anxiety, fever, or underlying illnesses affecting the respiratory system. Recognizing tachypnea is crucial in clinical practice as it can indicate distress or compromised respiratory function, prompting further evaluation and intervention.
