CCRN Obstructive Sleep Apnea Review
Obstructive sleep apnea is a potentially serious sleep disorder. It causes breathing to repeatedly stop and start during sleep.
There are several types of sleep apnea, but the most common is obstructive sleep apnea. This type of apnea occurs when your throat muscles intermittently relax and block your airway during sleep. A noticeable sign of obstructive sleep apnea is snoring.
Treatments for obstructive sleep apnea are available. One treatment involves using a device that uses positive pressure to keep your airway open while you sleep. Another option is a mouthpiece to thrust your lower jaw forward during sleep. In some cases, surgery may be an option too.

CCRN Obstructive Sleep Apnea Review – Causes
Obstructive sleep apnea occurs when the muscles in the back of your throat relax too much to allow normal breathing. These muscles support structures including the back of the roof of your mouth (soft palate), the triangular piece of tissue hanging from the soft palate (uvula), the tonsils and the tongue.
When the muscles relax, your airway narrows or closes as you breathe in and breathing may be inadequate for 10 seconds or longer. This may lower the level of oxygen in your blood and cause a buildup of carbon dioxide.
Your brain senses this impaired breathing and briefly rouses you from sleep so that you can reopen your airway. This awakening is usually so brief that you don’t remember it.
You can awaken with shortness of breath that corrects itself quickly, within one or two deep breaths. You may make a snorting, choking or gasping sound.
This pattern can repeat itself five to 30 times or more each hour, all night long. These disruptions impair your ability to reach the desired deep, restful phases of sleep, and you’ll probably feel sleepy during your waking hours.
People with obstructive sleep apnea may not be aware that their sleep was interrupted. In fact, many people with this type of sleep apnea think they slept well all night.

- During this sleep study, you’re hooked up to equipment that monitors your heart, lung and brain activity, breathing patterns, arm and leg movements, and blood oxygen levels while you sleep.
Home sleep apnea testing
- Under certain circumstances, your doctor may provide you with an at-home version of polysomnography to diagnose obstructive sleep apnea. This test usually involves measurement of airflow, breathing patterns and blood oxygen levels, and possibly limb movements and snoring intensity.
