Can home sleep study diagnose central sleep apnea?

Those with pre-existing conditions, such as lung disease, hypoventilation, heart failure, or other sleep disorders, such as restless legs syndrome, central sleep apnea or parasomnias, aren’t candidates for home testing.

Can central sleep apnea be misdiagnosed as obstructive sleep apnea?

Unfortunately, sleep apnea misdiagnoses are relatively common, often due to inaccurate home test results or self-diagnosing. There are also three different types of sleep apnea: obstructive, central, and complex.

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

How accurate are at home sleep studies?

The accuracy of home sleep apnea tests ranges widely, between 68\% and 91\%. The accuracy depends on the type of device used and whether you are at a high or low risk for having sleep apnea. The tests are significantly more accurate for people at a higher risk.

How common is central sleep apnea?

US frequency. Predominant central apnea is uncommon and is seen in less than 10\% of patients presenting for PSG. In the general population, the prevalence of central sleep apnea is less than 1\%. CSB-CSA has been reported in 25-40\% of patients with heart failure and in 10\% of patients who have had a stroke.

Can a sleep study test be wrong?

It is possible for a home sleep test to produce a “false-positive result.” About 15 percent of people without OSA are likely to receive a false-positive result. This is even more common in older adults who often have other medical problems or sleep disorders that affect sleep.

What neurological disorders cause central sleep apnea?

Central Sleep Apnea Risk Factors

• Congestive heart failure.
• Hypothyroid disease.
• Kidney failure.
• Neurological diseases, such as Parkinson’s disease, Alzheimer’s disease, and amyotrophic lateral sclerosis (ALS or Lou Gehrig’s disease)
• Damage to the brainstem from swelling (encephalitis), stroke, or injury.
