Lung Protective Mechanical Ventilation

Lung Protective Ventilator Settings[1] should be the default for all intubated patients, unless contraindicated. It has demonstrated mortality benefit for ARDS-like pulmonary conditions; limits barotrauma and decreases complications of high FiO2[2][3]

  1. Mode
    • Volume-assist control
  2. Tidal Volume
    • Start 6-8cc/kg predicted body weight[4]
      • Predicted/"ideal" body weight is used because a person's lung parenchyma does not increase in size as the person gains more weight.
    • Titrate down if peak pressure >30 mmHg
  3. Inspiratory Flow Rate (comfort)
    • More comfortable if higher rather than lower
    • Start at 60-80 LPM
  4. Respiratory Rate (titrate for ventilation)
    • Average patient on ventilator requires 120mL/kg/min for eucapnia
    • Start 16-18 breaths/min
    • Maintain pH = 7.30-7.45
  5. FiO2/PEEP (titrate for oxygenation)
    • Move in tandem to achieve:
    • SpO2 BETWEEN 88-95%
    • PaO2 BETWEEN 55-80
