Eupnea

In the human respiratory system, eupnea (Greek eupnoia; from eu, well + pnoia, breath) is normal, unlaboured ventilation, sometimes known as quiet breathing or resting respiration. In eupnea, expiration is an entirely passive process, employing the elastic recoil of the lungs.

• Apnea, absence of respiration
• Bradypnea, slow respiration
• Dyspnea, difficult respiration
• Tachypnea, fast respiration
