AB Obstructive  sleep  apnea/hypopnea  syndrome  (OSAHS)  and  central  sleep  apnea  (CSA)  are  both  classified  as  sleep-related  breathing  disorders.  OSAHS  and  CSA  share  some  risk  factors  and  physiological  bases  but  also  have  unique  features.  Each  disorder  is  associated  with  impaired  ventilation  during  sleep  and  disruption  of  sleep,  and  each  diagnosis  requires  careful  elicitation  of  the  patient’s  history,  physical  examination,  and  physiological  testing.  OSAHS,  the  more  common  disorder,  causes  daytime  sleepiness,  impairs  daily  function,  and  is  a  major  contributor  to  cardiovascular  disease  in  adults  and  to  behavioral  problems  in  children.  CSA  is  less  common  and  may  occur  in  combination  with  obstructive  sleep  apnea,  as  a  primary  condition,  or  secondary  to  a  medical  condition  (such  as  heart  failure)  or  medication.  Patients  with  CSA  often  report  frequent  awakenings  and  daytime  fatigue  and  are  at  increased  risk  for  heart  failure  and  atrial  fibrillation.
