This occurs regardless of the mechanical load on the respiratory system and no matter how strenuous or feeble the inspiratory muscle effort. Current data indicate that ACV is still the most frequently used mode in intensive care units (ICUs).1 Nowadays, the main reason for patients being admitted to an ICU is the need for mechanical ventilation,2 and the most common reason to initiate mechanical ventilation is acute respiratory failure.1,3,4 Approximately 60% of intubated, ventilated patients receive ACV.5 This percentage is similar for patients ventilated for decompensated chronic obstructive pulmonary disease (COPD),5 and even higher for those ventilated for acute respiratory distress syndrome (ARDS).6
