Step-by-step explanation:
Cheyne-Stokes breathing is a type of abnormal breathing pattern characterized by alternate periods of deep, rapid breathing followed by periods of shallow or no breathing. It is typically observed in individuals with certain medical conditions such as heart failure, brain damage, or respiratory disorders. During the periods of deep breathing, the body compensates for a build-up of carbon dioxide by increasing the respiratory rate. Then, during the periods of shallow or no breathing, the carbon dioxide levels decrease and the respiratory rate slows down.
