[Modes of mechanical ventilation during transferring the patient to spontaneous breathing].

Mechanical ventilation (MV) has become a general treatment in the intensive care unit in recent years. Mechanical ventilation is a resuscitation treatment; however MV causes many implications therefore it is to be finished as soon as the patient's condition begins improve. Modern transferring the patient to spontaneous breathing decreases implications number. Significant part of mechanical ventilation time (40%) is a time of weaning from mechanical ventilation. Weaning from MV is an economical, clinical and ethical problem. Many ventilation modes have introduced in clinical practice through the microprocessor technologies development. Supporting ventilation modes help to avoid some adverse effects of mechanical ventilation. The article deals with historical approaches development their advantages and limitations.
