A respiratory arrest is best defined as which of the following?

• A. A condition in which breathing stops
• B. A condition of rapid breathing with good oxygenation
• C. Breathing that is shallow but present
• D. A temporary pause in breathing during sleep

Answer: (A)

Respiratory arrest means there is no breathing at all—air is not moving in or out, so the body gets no oxygen and carbon dioxide can build up. It’s an emergency that needs immediate help and, if the person is unresponsive, CPR may be required. The other descriptions describe different breathing problems: rapid breathing with good oxygenation is fast breathing but adequate air exchange, not an arrest; shallow breathing means airflow is reduced but not completely stopped; a temporary pause during sleep sounds like sleep apnea, which occurs during sleep and isn’t the same as a sustained cessation of breathing.
