CSA (Central Sleep Apnea)
While some apneas are caused by a blockage or collapse of your upper airway, central sleep apnea is when your breathing stops but your airway is actually open. Even though the airway may be open, the automatic action of breathing stops because the communication between the brain and the body has been lost. See also: apnea; Obstructive Sleep Apnea (OSA)
