Tachypnea refers to which of the following?

Tachypnea is an abnormally rapid respiratory rate. It means breathing is happening faster than normal, typically defined in adults as more than about 20 breaths per minute. This focuses on rate, not depth of breathing, and it’s a sign that the body is trying to get more oxygen or remove more carbon dioxide quickly, often during distress, fever, anxiety, or underlying illness. Shortness of breath, or dyspnea, is a subjective sensation of not getting enough air, which can accompany tachypnea but isn’t the same thing. An irregular heartbeat points to a rhythm problem in the heart, not the speed of breathing. Breathing slowly, or bradypnea, is the opposite of tachypnea. Because tachypnea specifically denotes rapid breathing, it’s the best match.
