Question: 1 / 400

What might frequent RERAs indicate in a sleep study?

Healthy sleep patterns

Increased risk of insomnia

Potential sleep-disordered breathing

Frequent respiratory effort-related arousals (RERAs) observed in a sleep study suggest a potential issue with sleep-disordered breathing. RERAs occur when there is an increase in respiratory effort leading to an arousal from sleep, but without the full criteria required for apnea or hypopnea. The presence of numerous RERAs can indicate that the individual is experiencing episodes of insufficient airflow or breathing irregularities that may disrupt sleep quality.

This is significant because it can be a precursor or symptom of conditions such as obstructive sleep apnea, where breathing becomes impaired during sleep, leading to repeated awakenings. Observing RERAs necessitates further evaluation and possibly intervention to address what might be underlying sleep-disordered breathing. Understanding the implications of frequent RERAs allows healthcare providers to identify patients at risk and manage their sleep health effectively.
