Does anyone know if central sleep apnea (csa) can also cause reras? I had a sleep study which showed plmd, csa and numerous reras which were attributed to osa. I had less than 2 seconds of snoring the entire night and wondered how they decide what is the cause of reras. I had no osa events.
Central sleep apneas are caused due disorders or lesions in the brain. The peripheral system does not get the right impulses for respiration and hence the stoppage of respiration. As a result the person is aroused from sleep.
Obstructive events are characterized by continued thoracoabdominal effort in the setting of partial or complete airflow cessation, central events by lack of thoracoabdominal effort in this setting. Mixed events have both obstructive and central features.
