Tachypnea is defined as what?

Tachypnea is defined as what?

• A. slow, regular breathing
• B. rapid, deep breathing
• C. rapid, shallow breathing
• D. irregular breathing

Answer: (C)

Tachypnea means an abnormally fast respiratory rate, typically with shallow breaths. The key feature is rapid breathing, and in many clinical contexts the depth of each breath is shallow rather than deep, which helps distinguish it from other breathing patterns like hyperpnea (increased rate with deeper breaths). Normal adults breathe about 12–20 times per minute; tachypnea is when the rate is elevated above that. This is why the description of rapid, shallow breathing best fits tachypnea. Slow breathing describes bradypnea, rapid and deep describes hyperpnea, and irregular breathing describes patterns like Cheyne-Stokes, none of which define tachypnea.
