What term describes difficult or slow breathing?

• A. Apnea
• B. Dyspnea
• C. Obstruction
• D. Aspiration

Answer: (B)

The concept here is how we describe breathing difficulty. Dyspnea is the term for the subjective experience of not being able to breathe easily—feeling short of breath, having to work harder to breathe, or breathing that seems slow or labored. In sedation monitoring, recognizing dyspnea signals that ventilation may be stressed, even if breathing hasn’t fully stopped.

Apnea describes a pause in breathing, not just difficulty. Obstruction refers to a physical blockage of airflow, which is a specific cause of breathing problems rather than the general sensation of difficulty. Aspiration is the inhalation of material into the airway, risking obstruction or infection, but it’s not the term for the breathing sensation itself.

So the term that best matches "difficult or slow breathing" is dyspnea.
