[Technical aspects and innovations in non-invasive and invasive ventilation].

Abstract

Non-invasive and invasive ventilation have become essential for therapy in acute and chronic respiratory failure. More than one-third of patients in intensive care units receive invasive ventilation, and the number of ventilated patients in out-of-hospital care is also steadily increasing. While normalization of blood gases was considered the most significant goal in past decades, and the idea that mechanical ventilation also poses dangers played little role, the dominant thought at present is the application of ventilation from the most protective point of view possible. Because fundamental change in equipment technology is likely to be difficult, improvement of protective ventilation and further development of understanding of pathophysiologic processes in acute and chronic respiratory failure will continue to be of great importance in the future. This article summarizes different aspects of the technical basis of noninvasive and invasive ventilation and their practical implementation.
