If you’re experiencing regular sleep issues, insomnia, or just feel downright exhausted, you may have sleep apnea. Consulting your family doctor and undertaking a sleep study is the first step towards a more restful sleep.
Sleep apnea is extremely common, affecting roughly 5.4 million Canadians. The two types of sleep apnea are obstructive sleep apnea and central sleep apnea. It’s important to get properly assessed as the cause and treatment of every case of sleep apnea is unique.
Read on to learn about how to identify if you have sleep apnea, what type of sleep apnea you have, and how to treat it.
The main difference between central and obstructive sleep apnea is that the former is a cause of brain function while the latter is caused by a physical obstruction. Obstructive sleep apnea is far more common.
The following information may help you determine if you have sleep apnea. However, a consultation with a doctor will be the best path to lead you to a proper diagnosis. This may include your doctor advising you to take a sleep study. This means you would sleep overnight at a facility that can diagnose sleep apnea by monitoring your sleep state, eye movement, muscle activity, heart rate, breathing, airflow, and blood oxygen levels.
OSA is when your breathing is repeatedly halted during sleep for brief periods as your throat does not stay fully open. This can cause fragmented sleep. It can also lower the levels of oxygen in your blood, due to a lowered oxygen intake. Over time the lack of rest and oxygen depletion can lead to heart disease, hypertension, memory issues, depression or chronic anxiety.
There are several lifestyles and bodily factors that may increase your risk of developing OSA. Risk factors for OSA outlined by the National Sleep Foundation include:
Some of the most common symptoms of OSA are hard to identify on your own but may be identified by a partner or parent observing your sleep. These include:
Other symptoms are common to other medical conditions and are harder to identify on their own as being caused by OSA. These include:
The primary treatment for sleep apnea is a continuous positive airway pressure device (CPAP), better known as CPAP therapy. This device gently blows air into your airway during sleep through a mask you attach to your face.
Other treatment options include surgery to correct the underlying problem or an invasive hypoglossal nerve stimulation technique.
If the cause of your sleep apnea is your body weight, alcohol, or smoking, then a positive lifestyle change may also correct the underlying problem.
CSA is caused by a disruption of signals from the brain’s respiratory drive. Simply put, your brain is not able to tell your muscles to breath. Unlike OSA, risk factors for CSA are more related to brain injury, medical issues, or substance abuse issues. It can also result from living at high altitudes.
The signs and symptoms of CSA are the same as those of OSA. Your medical history and a proper sleep study will determine if you suffer from CSA.
Medical and lifestyle risk factors for CSA include:
For CSA, treatment can include the use of a CPAP machine. However, for those who have CSA and find that CPAP does not work for their issues may benefit from Adaptive Servo-Ventilation (ASV). This is an advanced variation of a CPAP machine that can detect a full stop in breathing and adjust the pressure to trigger a breath.
A hypopnea is when air intake during sleep is reduced but not stopped altogether. This can be caused by the same factors as OSA and CSA. Hypopneas are sometimes a precursor to developing sleep apnea but can remain a condition on their own.
Treatments for central hypopneas are similar to sleep apnea. This includes the use of a CPAP machine.
