Sleep apnea is a common, but potentially serious sleep disorder.
Sleep apnea is a condition when breathing repetitively stops and begins when sleeping. The popularity of sleep apnea evaluation at home is increasing because it is easier and less costly.
These testing devices help doctors assess blood oxygen levels, airflow, breathing patterns and heart rate. If the test results show a drop in oxygen level during apnea and later increases with awakenings, it means a patient may have sleep apnea.
Sleep apnea is known to increase cardiovascular mortality.
