It is caused by the mechanical forces associated with positive-pressure mechanical ventilation, which can cause damage to lung tissue.

➡️ Types:
- Barotrauma
- Volutrauma

Barotrauma is caused by high airway pressures that can cause a rupture of the alveoli or bronchi. Similarly, volutrauma is caused by high volumes of air being forced into small airways, which can cause lung tissue to stretch and damage. The symptoms of VILI range from mild dyspnea (shortness of breath) to severe respiratory distress. The longer a patient is on mechanical ventilation, the greater their chances are of experiencing this type of injury.

➡️ Lung Protective Strategies
- Smaller tidal volumes
- Low plateau pressures
- Low driving pressures
- Appropriate FiO2
- Appropriate levels of PEEP

These strategies are often used in patients with acute respiratory distress syndrome (ARDS), which is a disorder characterized by refractory hypoxemia, decreased lung compliance, and severe oxygen insufficiency. Ventilator-induced lung injuries are primarily caused by an increased transpulmonary pressure during positive-pressure ventilation. This pressure is the difference between alveolar pressure and pleural pressure.

When the transpulmonary pressure is increased, it can cause alveolar rupture and collapse of lung tissue. This explains why clinicians concluded that a lower transpulmonary pressure is associated with a lower risk of ventilator-induced lung injuries.
- Tidal volume 4–8 mL/kg
- Plateau Pressure less than 28 cmH2O 
- Driving pressure less than 15 cmH2O 
- FiO2 to maintain PaO2 55–80 mmHg
- FiO2 to maintain SpO2 88–95%
