There are three types of sleep apnea; each type is caused by a different set of conditions. The types include Obstructive Sleep Apnea (OSA), Central Sleep Apnea (CSA), and mixed sleep apnea.
Obstructive Sleep Apnea (OSA)
OSA manifests when the muscles at the back of your throat narrows or blocks the airways, completely or partially blocking the flow of air. Patients suffering from this condition therefore experience lapses in their breathing when sleeping – affecting the amount of oxygen received by the body. Their quality of sleep is hence compromised.
Central Sleep Apnea (CSA)
Unlike OSA, the airway is not blocked, but the brain does not send signals to the respiratory muscles in a way it would in a brain that functions normally. Therefore your breathing starts and repeatedly stops throughout the duration of your sleep.
Mixed Sleep Apnea
Mixed sleep apnea is a condition where a patient has both conditions of OSA and CSA.
