Sleep Apnea Defined

Obstructive Sleep Apnea (OSA)
Obstructive Sleep Apnea (OSA) is the most common form of sleep apnea. It occurs when tissues in the throat collapse and block the flow of air in and out of the lungs during sleep. there is no airflow despite efforts to breathe. People with OSA struggle to breathe again and again, making restful sleep impossible.

Central Sleep Apnea (CSA)
This results from the brain not signalling the body to breathe. There is no airflow because there is no effort to breathe. Sleep may also be disrupted by CSA.

Mixed Sleep Apnea
This is a combination of central apnea and obstructive apnea.

Possible Consequences of Untreated OSA
