What can be a consequence of mechanical ventilation if proper techniques are not followed?

The correct answer identifies the increased risk of lung injury as a consequence of improper mechanical ventilation techniques. When mechanical ventilation is not conducted correctly, various factors can lead to barotrauma, volutrauma, or atelectrauma, all of which can jeopardize lung tissue integrity. High airway pressures can lead to over-distention of alveoli, causing damage to the lung parenchyma. Incorrect tidal volumes or inappropriate ventilatory settings can lead to areas of the lung being either under-oxygenated or over-inflated, resulting in inflammatory responses and subsequent injury.

Inadequate ventilation strategies can also contribute to complications like ventilator-associated pneumonia and compromise the patient’s overall respiratory mechanics. Therefore, adhering to proper techniques is crucial in preventing these risks and ensuring patient safety during mechanical ventilation.

In contrast, the other options suggest positive outcomes of mechanical ventilation, which are less relevant in the context of improper technique. Improved patient stability, enhanced oxygen delivery, and improved lung compliance can indeed be achieved with appropriate mechanical ventilation; however, they are not relevant to the consequences of failing to use proper techniques.
