abnormal breathing with patterns of dyspnea and apnea
Cheyne–Stokes respiration Cheyne–Stokes respiration /ˈtʃeɪnˈstoʊks/ is an abnormal pattern of breathing characterized by progressively deeper, and sometimes faster, breathing followed by a gradual decrease that results in a temporary stop in breathing called an apnea. The pattern repeats, with each cycle usually taking 30 seconds to 2 minutes.[1] It is an oscillation of ventilation between apnea and hyperpnea with a crescendo-diminuendo pattern, and is associated with changing serum partial pressures of oxygen and carbon dioxide.[2]
