Prevalence

Central Sleep Apnea Syndrome (CSAS) is not common in the general population. Patients with predominantly CSAS comprise less than 10 percent of patients with sleep apnea in most sleep laboratory populations.1 (Most patients with CSAS also have some obstructive sleep apnea events as well.)

CASA is present in approximately 25 to 40 percent of patients who have chronic heart failure.2 CSAS is also more common in individuals who live at higher altitudes.3 CSAS occurs in about 10-20 percent of patients on chronic opiates.4
