Quizplus · Accepted Answer

Ventilator dependence is more likely to occur when there is arterial hypoxemia (2), malnutrition (3), and cardiovascular instability (4), as these conditions impair the body's ability to maintain adequate oxygenation and perfusion, and to recover from respiratory failure, necessitating prolonged mechanical ventilation support.
