[Recruiting maneuver used in the treatment of respiratory heart failure in cardiosurgical patients].

The possibility of performing the recruiting artificial ventilation technique with a high plateau and positive end-expiratory pressure was studied in 32 cardiosurgical patients, including those with cardiovascular insufficiency. The lung opening maneuver, by using the artificial ventilation adjustable by pressure and the monitoring peak pressure, PDKV, tidal volume, and dynamic compliance, by accurately determining the points of opening and closure is the method of choice in alveolar recruitment. This method permits a significant improvement of arterial oxygenation and dynamic compliance of the lung in patients with acute respiratory failure. This maneuver using the high airway pressures adversely affects hemodynamics particularly in patients with lowered reserves of the cardiovascular system. In this connection, a careful monitoring of hemodynamic parameters is required for the timely provision of cardiotonic and vasopressor support.
