How Many people use C.P.A.P. Machines?

As of recent estimates, approximately 3-4 million people in the United States use CPAP (Continuous Positive Airway Pressure) machines to treat obstructive sleep apnea. Globally, the number is much higher, with millions more relying on CPAP therapy for better sleep and health. The prevalence of sleep apnea and the growing awareness of its treatment options continue to drive the use of CPAP devices.
