In general population, the treatment of SA with CPAP improves oxygenation during sleep and quality of life [10]. In the ESRD population, CPAP was used in a very preliminary study on 8 patients with some improvement in nocturnal oxygenation and 5 of 6 patients reported improved daytime alertness [11]. Unfortunately, CPAP application itself may be stressful, poorly tolerated and so disturb night sleep.
