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.
If you have been diagnosed with sleep apnea, you have likely been introduced to at least one of the possible treatment options. The most common (and effective) therapy is continuous positive airway pressure (CPAP). You may also be curious to know the difference between two similar treatment options: CPAP and BiPAP (or bilevel) therapy. Discover more information about these therapy devices and which one might be right for you.
