Sleep Apnea

Sleep apnea refers to breathing pauses because your airways are blocked or partly blocked while you sleep. These breathing pauses, called apneas or apnea events, can last 10 seconds or longer. People with sleep apnea can stop breathing hundreds of times each night, and this results in disrupted sleep and low levels of oxygen.

People with sleep apnea often do not feel rested in the morning which can lead to daytime sleepiness and trouble thinking clearly. Untreated sleep apnea can increase risk of car or work accidents, cardiovascular disease, high blood pressure and early death.

Main types of sleep apnea

Understanding the types

Most common

Obstructive Sleep Apnea (OSA)

Occurs when tissues at the back of your throat collapse, and your airways are blocked or partly blocked. OSA is the most common form of sleep apnea.

Central

Central Sleep Apnea

Happens when the brain has trouble controlling your breathing and fails to signal the muscles needed to breathe.

Mixed

Mixed or Complex Sleep Apnea

When you have both central and obstructive sleep apnea. Each sleep apnea episode usually begins with no breathing effort (Central Sleep Apnea). The breathing effort starts, but the airway is blocked (Obstructive Sleep Apnea).

Signs/Symptoms

Recognising sleep apnea

The two main symptoms are:

Excessive daytime sleepiness

Not feeling rested after a night's sleep

Loud snoring with pauses in breathing

Shortness of breath

Other symptoms or conditions include:

Waking with a dry mouth

Morning headache

Irritability

Gasping or choking during sleep

Lack of concentration

When awake

High blood pressure

Diabetes

Heart, liver and kidney disease

Depression

Untreated sleep apnea risks:

High blood pressure or Type II Diabetes

increased risk of high blood pressure, stroke, Alzehiemers and metabolic conditions like diabetes. It has been linked to worse outcomes for those with pre-existing health conditions.

Poor memory and concentration

Greater risk of causing a motor vehicle accident

Diagnosis

Getting a proper diagnosis

It is essential to get a proper diagnosis if you feel like you may have sleep apnea. Speak with your family doctor about your concerns and ask for a diagnosis. Your doctor will examine you, ask about your past health, and perform tests to find out what’s causing your sleep apnea.

  • Polysomnography (PSG) / Level 1 Testing A monitored method of diagnosing sleep apnea, and other sleep problems. It is an overnight test in a sleep lab where your sleep is monitored to gather data about your sleep stages and cycles, oxygen levels, heart rate, body movements and breathing patterns. A Certified Sleep Physician or sleep doctor will explain the results and suggest treatment if needed.

  • Home Sleep Apnea Test (HSAT) / Level 3 Testing Performed at your home to assess data about your oxygen levels and breathing patterns. Portable monitors will record information about your breathing while you are sleeping. When the test is completed, return the machine to the clinic to be reviewed. A sleep doctor will interpret the results and determine if a follow-up for treatment is required.

Treatment

Treatment options

The main treatment for sleep apnea is Positive Airway Pressure (PAP) like CPAP or BPAP machines that prevent your airways from closing during sleep.

Managing your sleep apnea is the first step to maintaining your health and regaining your quality of life. Consider help from your family, friends, and healthcare professionals such as your sleep doctor, family doctor, sleep apnea health professional/educator, and pharmacist. It is important to keep them informed about any changes or needs you might have.

Sleep apnea is often treated with a Continuous Positive Airway Pressure (CPAP) machine that prevents your airways from closing during sleep. Oral or nasal breathing devices may assist with sleep apnea.
