Modes of Mechanical Ventilation
- Modern mechanical ventilation modes fall into controlled and spontaneous categories based on patient versus machine control.
- Controlled modes dictate breath pattern; spontaneous modes let the patient set their own pattern with pressure support.
Initial Ventilator Settings
- Start intubated patients on volume control with a tidal volume of 400-500 mL and respiratory rate 10-16.
- Use a PEEP of 5 and FiO2 around 60%, adjusting oxygen to maintain saturations above 92%.
Adjust Ventilator Based on Blood Gas
- Adjust minute ventilation by increasing respiratory rate first over tidal volume to correct high CO2.
- Decrease FiO2 when PO2 is above 90 to avoid oxygen toxicity and lung injury.
