Mechanical ventilation (MV) is crucial for respiratory insufficiency but can harm lungs, especially in acute respiratory distress syndrome (ARDS). Lung protective ventilation strategies are essential to minimize ventilator-induced lung injury and secondary inflammation.
Area of Science:
- Intensive care medicine
- Pulmonology
- Critical care
Background:
- Mechanical ventilation (MV) is a life-saving therapy for respiratory failure.
- MV can cause ventilator-induced lung injury (VILI) due to mechanical stress.
- Acute respiratory distress syndrome (ARDS) presents with heterogeneous lung damage, complicating MV.
Purpose of the Study:
- To highlight the risks of MV in respiratory insufficiency.
- To emphasize the need for protective ventilation strategies in ARDS.
- To underscore the importance of evidence-based concepts in MV.
Main Methods:
- Review of existing literature on MV and VILI.
- Analysis of pathophysiological processes induced by MV.
- Focus on ARDS pathophysiology and its implications for ventilation.
Main Results:
- MV, while essential, can exacerbate lung injury.
- Heterogeneous lung damage in ARDS increases VILI risk.
- Secondary inflammatory responses can affect multiple organs.
Conclusions:
- Lung protective ventilation is critical for managing patients on MV.
- Evidence-based strategies are necessary to mitigate MV-induced harm.
- Minimizing VILI is paramount in intensive care settings.
