Sleep Apnea, Central
Dynamic Carbon Dioxide (CO2) Administration for Sleep Apnoea
Normally breathing is controlled by a reflex that responds to the levels of carbon dioxide (CO2) in the blood. In heart failure, where the heart muscle is damaged and therefore does not pump as well, this reflex is exaggerated.
