AB Controlled  mechanical  ventilation  (CMV)  is  traditionally  provided  via  an  artificial  airway  to  completely  unload  a  patient’s  work  of  breathing  and  assure  adequate  gas  exchange  during  the  acute  phase  of  respiratory  insufficiency,  until  the  underlying  respiratory  function  has  resolved.1  The  criteria  used  to  determine  when  to  terminate  mechanical  ventilation  are  essentially  based  on  the  clinical,  and  often,  subjective  assessment  of  the  intensive  care  physician  or  on  standardized  weaning  methods.2,3  The  actual  process  of  weaning  the  patient  from  CMV  is  carried  out  by  allowing  spontaneous  breathing  attempts  with  a  T  piece  or  continuous  positive  airway  pressure  (CPAP)  or  by  gradually  reducing  mechanical  assistance.4,5  Not  surprisingly,  gradual  reduction  of  partial  ventilator  support  benefits  only  patients  who  have  difficulty  in  sustaining  unassisted  breathing.4  Although  introduced  as  weaning  techniques,  partial  support  modes  have  become  standard  methods  of  providing  primary  mechanical  ventilatory  support  in  critically  ill  patients.
