Familiarity with the concept of permissive hypercapnia contributed to this change, helping physicians to overcome the old and stringent mindset on arterial blood gases.1–4 Tidal volume or minute ventilation requirements were increasingly regarded as secondary goals during mechanical ventilation and the apparent security provided by PCV, keeping airway pressures under strict limits, gained broader acceptance. Recent surveys in intensive care units demonstrate that PCV is now used in up to 25% of ventilated patients, usually in the most severe cases5,6 (including pediatric patients7). Studies, describing the implications of PCV on the cardiovascular system, work of breathing, regional mechanics, risks of VILI, and recruitment maneuvers are now available. These studies increase physician comfort in moving away from volume-controlled ventilation.
