Open lung concept

from Wikipedia, the free encyclopedia

The open lung concept is a ventilation pattern postulated by Burkhard Lachmann that is used in intensive care medicine . Lung areas affected by atelectasis are made accessible again for gas exchange by means of an inflation maneuver ( Lachmann maneuver ) with briefly high ventilation pressure . Then the free circulation of air is ensured by applying a high end-expiratory pressure level ( PEEP ).

The concept is shaped by Lachmann's summarizing sentence: " Open up the lung and keep the lung open ".

Advantages and disadvantages

By opening lung areas that are temporarily not ventilated, the oxygen saturation in the blood is improved. In addition, the larger accessible surface reduces the pressure on individual alveoli . However, there is a risk of injury to the lungs ( pneumothorax ) and the associated accumulation of air in the pleural space . In addition, the blood pressure in the pulmonary circulation increases and the circulation can collapse.
