Sleep Apnea

(Obstructive Apnea; Central Apnea; Mixed Apnea)

 

Definition

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:

  • Obstructive
  • Central
  • Mixed

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.

 

Causes    TOP

Major causes depend on the type of sleep apnea:

  • Obstructive—Muscles in the body to relax during sleep. This can let soft tissue in the back of the throat and mouth to sink toward the throat. If the tissue blocks the airway it will stop normal breathing until it was cleared.
  • Central—Breathing is controlled by signals from the brain. If the signals are not working properly, breathing can be slowed or paused.
  • Mixed—Both soft tissue and nerve signals are causing problems.

Risk Factors    TOP

Sleep apnea is more common in:

  • Men
  • Adults over 40 years old

Other factors that may increase the chances of sleep apnea:

  • Excess weight or obesity
  • Large neck circumference
  • Family history of apnea
  • Structure problems of the nose or throat such as:
  • Hypothyroidism
  • Asthma
  • Certain medications, such as sedatives, opioids, and sleeping aids
  • Excess alcohol intake
  • Smoking
  • Sleeping without dentures (if you have them)
  • Heart failure (central sleep apnea)
  • Pregnancy
 

Symptoms    TOP

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:

  • Fatigue and sleepiness throughout the day
  • Unrefreshing sleep
  • Morning headaches
  • Poor concentration or problems with memory
  • Irritability or short temper

Untreated sleep apnea has been linked to other health problems, such as:

  • High blood pressure
  • Cardiovascular disease
  • Depression
  • Stroke
  • Kidney disease

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.

 

Diagnosis    TOP

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:

  • Eye and muscle movements
  • Brain activity using an EEG
  • Heart rate
  • Breathing pattern and depth
  • Amount of oxygen that reaches your blood

These details will help your doctor see how severe the sleep apnea is.

 

Treatment    TOP

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:

  • If you are overweight, lose excess weight. Work with your doctor or a registered dietitian to help create a plan.
  • Avoid sedatives, opioids, sleeping pills, alcohol, and tobacco. They will make your tissue relax and make apnea worse.
  • Try sleeping on your side instead of on your back. Soft tissue will fall directly into your airway if you are on your back.
  • Use pillows to help you prop yourself into a better position when sleeping.

Oral Appliances

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    TOP

Surgery may be helpful for some with obstructive sleep apnea. It can be used to shrink or remove extra tissue.

Options include:

  • Maxillomandibular advancement—lower jawbone is repositioned forward
  • Adenotonsillectomy—adenoids and tonsils are removed
  • Uvulopalatopharyngoplasty —extra soft tissue is removed from the nose and/or throat

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.

Medications    TOP

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.

 

Prevention    TOP

You may be able to prevent sleep apnea by maintaining a healthy weight.
