AB “Arterialization”  of  venous  blood  requires  matching  of  the  distribution  of  air  and  blood  within  the  lung,  thereby  ensuring  effective  gas  exchange  across  the  alveolar–capillary  membrane*.  Arterialization  comprises  a  series  of  interrelated  processes  that  begin  with  the  mechanical  performance  of  the  ventilatory  apparatus—that  is,  the  lungs  and  the  chest  wall,  including  the  rib  cage,  diaphragm,  and  abdominal  wall.  Ventilation  is  critical  for  replenishing  fresh  air  to  the  lungs  for  gas  exchange.  Although  the  function  of  each  component  of  the  lung  and  of  the  chest  bellows  can  be  deranged  by  injury  or  disease,  the  design  of  the  ventilatory  apparatus  provides  for  considerable  reserve.  As  a  result,  mechanical  derangements  are  usually  quite  severe  by  the  time  clinical  symptoms  appear  or  arterial  blood-gas  levels  become  abnormal.
