Abstract

We report a patient with congestive heart failure secondary to dilated cardiomyopathy who demonstrated central sleep apnea with Cheyne–Stokes breathing (CSA-CSB) on polysomnography. He was put on positive airway pressure therapy with adaptive servoventilation (ASV), which failed to correct the CSA-CSB condition. A backup rate was added with ASV, which eliminated apnea but periodic breathing persisted. Finally, enhanced expiratory rebreathing spacewas added and titrated with ASV to achieve normocapniausing transcutaneous CO2 monitoring that successfully stabilized the patient\'s breathing.
