What best describes respiratory arrest?

• A. A condition where a person is not breathing but may still have a pulse.
• B. A condition where the heart stops beating completely
• C. A condition where breathing is rapid and deep
• D. A condition with spasms of the chest

Answer: (A)

Respiratory arrest means the person has stopped breathing, but a pulse may still be present. This distinguishes it from cardiac arrest, where the heart stops beating and there is no pulse. When breathing stops, oxygen isn’t getting into the lungs and the body can’t circulate oxygen-rich blood efficiently, so immediate action is needed: provide rescue breaths to supply oxygen and, if there is no pulse, begin CPR. The other descriptions describe either no heartbeat with a likely pulse absent (cardiac arrest), rapid and deep breathing (hyperventilation or tachypnea), or chest wall spasms, which don’t match the situation of not breathing with a possible pulse.
