Settings of ventilator should aim for "specific patient goals"
Generic settings
     FiO2     100%
     Mode     ACV or SIMV
     Rate     10 bpm (titrate to goal)
     Tidal volume (8-10 mL/kg IBW)
     PEEP   5
     PS      10

Adjusting settings
     If PaO2 is too low, increase PEEP
     If PaCO2 is too low, decrease rate

Positive End-Expiratory Pressure (PEEP)
     Major function is to increase the mean airway pressure
     Increases oxygenation (in most patients) by:
          Improving atelectasis
          Decreasing shunt
          Increasing Functional Residual Capacity (FRC)
     Has negative consequences
          Can decrease blood pressure (decr CO)
          Can worsen dead space (incr PaCO2)
