It is stated in literature that the pressure control ventilation malaties have known advantages over the volumen control modalities, mainly from the hemodynamic point of view. Starting from this criterion, 30 patients who were admitted at the Intensive Care Unit of the Center of Medical and Surgical Research in January, 1996, and that required mechanical ventilation as part of the treatment were studied. These patients were hemodynamically stable and had no history of respiratory affections. They were coupled to an artificial respirator (Servo 900 C or Servo 300) by endotracheal tube and were ventilated for an hour under volume control regime. Variables such as compliance, intrapulmonary pressures, hemodynamic data (FC, PA, PVC, diuresis) and gasometric data were checked at the end. During the second hour they were ventilated under pressure control regime and the same parameters were evaluated. It was proved that mechanical pressure control ventilation produced less hemodynamic repercussions in our patients.
