What does tachypnea refer to?

Tachypnea refers to an abnormally rapid breathing rate. This condition can be observed in various situations, such as during fever, exercise, or in response to conditions that affect the lungs, such as infections or chronic obstructive pulmonary disease (COPD). The definition is rooted in the Greek prefix "tachy-" meaning swift or fast, combined with "pnea," which pertains to breathing. A heightened respiratory rate may indicate that the body is trying to obtain more oxygen or expel carbon dioxide more quickly, reflecting an underlying physiological response to stress or illness. Understanding tachypnea is essential in a Drug Recognition Expert context, as certain substances may influence breathing rates, contributing to its significance in assessing drug effects on individuals.
