What is the major goal of lung protective ventilation strategies?

The major goal of lung protective ventilation strategies centers around minimizing lung injury. These strategies are essential in the management of patients with acute respiratory distress syndrome (ARDS) and other forms of lung injury that can occur due to mechanical ventilation. By utilizing lower tidal volumes and maintaining an appropriate level of positive end-expiratory pressure (PEEP), lung protective ventilation aims to prevent over-distension of alveoli and barotrauma, which can lead to further pulmonary complications.

This approach focuses on maintaining adequate ventilation and oxygenation while safeguarding the pulmonary architecture from the damaging effects of traditional mechanical ventilation methods that use higher tidal volumes. Consequently, minimizing lung injury not only helps preserve the structural integrity of the lungs but also improves the overall outcomes for patients, reducing the duration of ventilation and the length of stay in intensive care settings.

In contrast, while improving gas exchange, optimizing oxygen delivery, and enhancing patient comfort are important goals in the context of respiratory support, they often come as secondary benefits of minimizing lung injury. By protecting the lungs through careful management of ventilatory settings, gas exchange and oxygen delivery can also be optimized effectively, which leads to a more favorable overall condition for the patient.
