Obstructive Sleep Apnea (OSA) is the most common type of sleep apnea. It occurs when the muscles in the throat relax too much, causing a blockage in the airway. This type is often associated with snoring and is typically managed with a CPAP machine or other therapies.
Central Sleep Apnea (CSA) is less common and occurs when the brain fails to send proper signals to the muscles that control breathing. It is often linked to underlying medical conditions and may require specialized treatments.
Complex Sleep Apnea Syndrome, also known as treatment-emergent central sleep apnea, is a combination of obstructive and central sleep apnea. It can occur when obstructive sleep apnea is treated, but central sleep apnea persists.
