How Well It Works
CPAP is effective for treating sleep apnea:
• Research shows that continuous positive airway pressure (CPAP) decreases daytime sleepiness, especially in those who have moderate to severe sleep apnea.1, 2, 3
• Studies show that in people who have moderate to severe sleep apnea, nasal continuous positive airway pressure (NCPAP) lowersblood pressure during both the day and the night.4, 5
• CPAP is better than other nonsurgical methods for treating obstructive sleep apnea.6
• People with coronary artery disease who use CPAP for sleep apnea are less likely to have heart problems such as heart failure.7
