What does the term "hypopnea" mean in polysomnography results?

• A. A partial cessation of breathing, characterized by reduced airflow
• B. A complete cessation of breathing for longer than 10 seconds
• C. A phase of deep sleep with minimal movements
• D. An increased rate of breathing during sleep

Answer: (A)

Hypopnea refers to a partial cessation of breathing that is characterized by a reduction in airflow during sleep. Specifically, it is identified as a decrease in airflow of at least 30% from baseline for a duration of at least 10 seconds, accompanied by a reduction in oxygen saturation or an arousal from sleep. This condition is particularly important in the context of sleep studies because it can contribute to fragmented sleep and can be a significant factor in diagnosing sleep apnea. Understanding hypopnea is essential for evaluating sleep quality and understanding how various breathing disturbances can affect health. In a polysomnography (PSG) study, identifying episodes of hypopnea helps clinicians assess the severity of sleep-related breathing disorders and develop appropriate treatment plans for affected individuals. Other terms, such as complete cessation of breathing or phases of sleep, reference different and distinct phenomena from hypopnea and do not accurately capture the specific definition.
