How can you tell the difference between central and obstructive sleep apnea?

Two main types of sleep apnea include obstructive sleep apnea (most common) and central sleep apnea. OSA is where your upper airway gets partially or completely blocked while you sleep. Central sleep apnea (CSA), cessation of respiratory drive results in a lack of respiratory movements.

Will a sleep study show central sleep apnea?

In a split-night sleep study, you’re monitored during the first half of the night. If you’re diagnosed with central sleep apnea, staff might wake you and give you positive airway pressure for the second half of the night. Polysomnography can help your doctor diagnose central sleep apnea.

Which test is used to diagnose central and obstructive sleep apnea?

Tests to detect sleep apnea include: Nocturnal polysomnography. During this test, 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.

What is the root cause of central sleep apnea?

Central sleep apnea results when the brain temporarily stops sending signals to the muscles that control breathing. The condition often occurs in people who have certain medical problems. For example, it can develop in someone who has a problem with an area of the brain called the brainstem, which controls breathing.

What does Central sleep apnea feel like?

People with central sleep apnea often have severe fatigue, daytime drowsiness and irritability. You might have difficulty concentrating and find yourself falling asleep at work, while watching television or even while driving.

What may happen if the sleep apnea is not diagnosed?

Sleep is an important part of the body’s recovery process; frequent interrupted sleep can raise stress levels, resulting in high blood pressure and an increased risk of heart disease. Sleep apnea has also been linked to stroke and Type 2 diabetes.
