Which of the following is classified as abnormally rapid, deep, or labored breathing?

The term that describes abnormally rapid, deep, or labored breathing is hyperpnea. This condition often occurs as a result of increased metabolic demand, such as during exercise or in response to certain medical conditions, leading to the need for greater oxygen intake and carbon dioxide removal. Hyperpnea is characterized by a significant increase in both the depth and rate of breaths, which aligns with the concept of labored breathing. In contrast, hyperventilation refers to rapid breathing that can lead to decreased carbon dioxide levels, but it may not necessarily involve deep breaths. Hypopnea indicates abnormally shallow breathing, and apnea describes a temporary cessation of breathing altogether. Thus, hyperpnea accurately captures the essential attributes of rapid and deep breathing, making it the correct answer.
