AB  - Critically  ill  patients  require  arterial  blood  gas  (ABG)  analysis  to  assess  oxygenation  and  ventilation  due  to  limitations  of  noninvasive  oximetry  measurements.  Below  a  pO2  of  60  mm  Hg  corresponding  to  an  O2  saturation  of  80%,  the  oxyhemoglobin  saturation  curve  is  steep  and  large  changes  in  oximetry  may  mean  small  changes  in  oxygenation.  Below  this  level  oximetry  may  not  correlate  with  oxygenation,  and  an  arterial  blood  gas  (ABG)  should  be  obtained  (Table  122-1).
