(Obstructive Apnea; Central Apnea; Mixed Apnea)
by Jenna Hollenstein, MS, RD
Sleep apnea is a disorder with pauses in breathing while you are asleep. These pauses can last for 10-30 seconds at a time. During one night, breathing may stop up to 400 times.
There are 3 types of sleep apnea:
With any of sleep apnea, the brain will sense the pause in breathing and wake you up. You may not be fully awake and often do not remember in the morning. However, waking breaks the sleep cycle. Poor sleep can make you tired during the day. Over time this will also lead to other serious medical conditions like high blood pressure or depression.
Major causes depend on the type of sleep apnea:
Risk Factors TOP
Sleep apnea is more common in:
Other factors that may increase the chances of sleep apnea:
Your partner may notice loud snoring or that you stop breathing at night. You may notice that you wake often during the night.
Regular sleep apnea can lead to:
Untreated sleep apnea has been linked to other health problems, such as:
Sleep apnea also increases the risk of car accidents. It is most likely due to lack of sleep. If you are sleepy during the day avoid driving or using hazardous equipment.
The doctor will ask about your symptoms and health history. If the doctor thinks it may be sleep apnea you will be sent for an overnight sleep study. Most will take place in a clinic but some may be done at home.
Polysomnography during the study will measure:
These details will help your doctor see how severe the sleep apnea is.
Treatment will decrease symptoms so that you can sleep better. This will also reduce risk factors for other health conditions. The exact treatment will depend on the type of sleep apnea and how severe it is.
Managing Mild Apnea
Mild obstructive apnea may be relieved with some of the following:
Oral appliances are small devices you put in your mouth. They will keep the lower jaw in a forward position. This position pulls the tongue away from the airway. It may be helpful for those with mild sleep apnea. The devices may also be used for those with moderate obstructive sleep apnea who cannot use CPAP therapy.
Mechanical Therapy TOP
Continuous positive airway pressure (CPAP) is a machine that gently blows air into your airway to help keep it open. The air is delivered through a mask that you wear while sleeping. CPAP will help you manage sleep apnea but it does not cure it. If you stop using CPAP, the sleep apnea will return immediately.
Oxygen may also be added at night with CPAP. It may be needed if the level of oxygen in the blood falls too low during sleep.
Surgery may be helpful for some with obstructive sleep apnea. It can be used to shrink or remove extra tissue.
A less available option is called phrenic nerve stimulation. A device is implanted under the skin and sends signals to the phrenic nerve. This nerve controls a large muscle that helps draw air into the lungs. This options is still being assessed.
Certain medicine may be used to reduce daytime symptoms. Other medicine may need to be changed or stopped if they are making sleep apnea worse.
