Effects of nCPAP treatment over reaction time and sleepiness levels during vigilance.

Several studies have shown that sleep fragmentation not only increases daytime sleepiness, but also deteriorates reaction time. Obstructive sleep apnea syndrome (OSAS) is characterized by interruptions in normal sleep patterns. Nasal Continuous Positive Airway Pressure (nCPAP) is the most frequently used treatment for OSAS.
