When We Stop Breathing at Night…

The most common type of sleep apnea is called obstructive sleep apnea. It happens because the muscles in your throat relax, blocking the flow of air to your lungs. Your airway might be completely blocked or only partly blocked. When you stop breathing, the amount of oxygen in your blood drops. Your brain recognizes this and makes your body start breathing again.
If you have sleep apnea, there are times during the night when you stop breathing for 10 seconds or longer.

Your doctor needs to know how often there is a pause in your breathing. This helps to determine how severe your problem is. You might be asked to stay overnight in a sleep laboratory. Or your doctor might ask you to have your breathing measured at home.
Here’s one guide that doctors use:
-If your breathing is affected between five and 15 times an hour, you have mild sleep apnea.
-If your breathing is affected between 16 and 30 times an hour, you have moderate sleep apnea.
-If your breathing is affected more than 31 times an hour, you have severe sleep apnea.

People with severe sleep apnea may be at an increased risk of high blood pressure, heart disease and stroke and dying early.
