Goals of Ventilation

  • Adequate ventilation (acceptable pH usually > 7.32)
  • Acceptable oxygenation (pO2 > 60 or sat > 90%)
  • Prevent VILI (ventilator-induced lung injury):
    • Avoid oxygen free radical toxicity (keep FIO2 < 0.5)
    • Avoid barotrauma (keep peak pressures < 35 cm)
    • Avoid volutrauma (keep Vt ~ 6 cc / kg)
  • Patient comfort
  • Earliest possible wean
