A Case of Sleep Apnea Syndrome in Amyloidosis Treated With Adaptive Servo-Ventilation

A 48-year-old man, with a history of systemic light-chain amyloidosis and heart failure, presented with snoring during sleep. He underwent sleep examination by portable monitor, which revealed sleep apnea syndrome (SAS) with an apnea-hypopnea index (AHI) 45.4/h. He started auto-adjusting continuous positive airway pressure (auto-CPAP) treatment. The memory stick of the CPAP machine showed that he used auto-CPAP for an average 5.5  h/night, and that the AHI was 48.3/h. The 4% oxygen desaturation index determined from pulse oximetry was 6.05/h during auto-CPAP treatment.
