The DRS stands for Drag Reduction System, which enables a car to open its rear wing to limit the downforces on the car. This increases the car's theoretical performance and in theory facilitates passing.
Sleep apnea facts. 1  Sleep apnea is defined as a reduction or cessation of breathing during sleep. 2  The three types of sleep apnea are central apnea, obstructive apnea, and a mixture of central and obstructive apnea.  Central sleep apnea is caused by a failure of the brain to activate the muscles of breathing during sleep.
The ACP also strongly recommends continuous positive airway pressure, or CPAP. This is typically the first-line treatment for people with sleep apnea, because weight loss can be so hard to achieve. CPAP is a mask or device that fits over the nose and mouth. It blows air into the airways to keep them open at night.
