What are the potential complications of mechanical ventilation in ARDS?

The correct answer focuses on ventilator-associated pneumonia, barotrauma, and lung injury as potential complications of mechanical ventilation in patients with ARDS.

Ventilator-associated pneumonia is a significant risk due to the endotracheal tube providing a direct pathway for bacteria from the environment into the lungs, leading to infection, which can complicate the underlying condition of ARDS and prolong recovery.

Barotrauma occurs when excessive pressure is applied to the airways during mechanical ventilation, leading to the rupture of alveoli and potential pneumothorax. This pressure must be carefully monitored to prevent such injuries, particularly in the context of already compromised lung tissue in ARDS patients.

Additionally, lung injury can be exacerbated by mechanical ventilation, especially if high tidal volumes or excessive inspiratory pressures are used, contributing to ventilator-induced lung injury (VILI). This type of injury worsens the patient's condition and complicates the management of ARDS.

Other options do mention serious complications, but they do not align as closely with the typical complications seen specifically related to mechanical ventilation in the context of ARDS. Understanding these specific risks associated with mechanical ventilation helps guide clinicians in providing safer and more effective care for patients experiencing ARDS.
