With computer feedback systems, many modern ventilators allow the operator to make fine adjustments in tidal volume, airway pressures, and the timing of the respiratory cycle. The desired result is improved ventilator-patient interaction and limitation of ventilator-induced lung injury. These newer methods of mechanical ventilation are often based on attractive physiologic hypotheses, and they are interesting to implement. Each method has its proponents, but objective evidence has failed to show that any of the alternative methods of ventilation is more successful than conventional mechanical ventilation with proper attention to tidal volume. Most clinicians use alternative methods of ventilation only in cases when conventional mechanical ventilation has failed. [10]
