You are managing a patient with severe pneumonia who was intubated and placed on positive pressure mechanical ventilation two hours ago. The goals of mechanical ventilatory support for this patient include: Stabilizing the chest wall Maintaining acceptable lung volumes Ensuring adequate tissue oxygenation Reducing the level of WBCs in the sputum Reduction in the work of breathing (WOB)
