Central sleep apnea (CSA) or central sleep apnea syndrome (CSAS) is a sleep-related disorder in which the effort to breathe is diminished or absent, typically for 10 to 30 seconds either intermittently or in cycles, and is usually associated with a reduction in blood oxygen saturation.[1][2] CSA is usually due to an instability in the body's feedback mechanisms that control respiration.[3] Central sleep apnea can also be an indicator of Arnold–Chiari malformation.[4]
