The suffix -pnea is derived from the Greek word pnoia, which means ‘breath’ or ‘breathing.’ In medical terminology, it is used to describe various conditions related to breathing. For example:
- Apnea: A temporary cessation of breathing, often during sleep.
- Dyspnea: Difficulty or labored breathing.
- Eupnea: Normal, unlabored breathing.
- Hyperpnea: Increased depth and rate of breathing, often due to physical exertion.
- Tachypnea: Abnormally rapid breathing.
Understanding these terms can help in recognizing and describing different breathing conditions accurately.
