During a sleep study, what does a high arousal index indicate?

• A. Adequate sleep quality
• B. Frequent nighttime awakenings
• C. Low oxygen levels
• D. Prolonged uninterrupted sleep

Answer: (B)

A high arousal index during a sleep study signifies frequent nighttime awakenings. This index measures the number of times a person awakens or has brief arousals during their sleep cycle. A higher arousal index indicates that the individual is experiencing disturbances during sleep, which can lead to fragmented sleep and reduced overall sleep quality. Monitoring the arousal index is essential, as elevated levels can provide insight into potential sleep disorders such as insomnia or sleep apnea, where frequent awakenings disrupt prolonged periods of rest. Recognizing this aspect is crucial for creating effective treatment plans and improving sleep health.
