Embodiment Construction

[0062] figure 1 An example of a ventilator device 1 according to the present disclosure is shown in a schematic manner. choose figure 1 to illustrate the principles of the present disclosure. It should be emphasized that, figure 1 is just one example, and ventilator devices can vary widely. Therefore, even ventilator devices that appear schematically quite different will be within the scope of the present disclosure, provided they contain all the features of the corresponding independent claims. A ventilator device 1 is connected to a subject 2, shown here in the form of a pair of lungs. A subject may eg be a human or an animal. The connection may be, for example, via the mouth, nose, trachea, etc. to the airway of the subject.

[0063] The ventilator device 1 may comprise a pressure regulating device 3 arranged to apply pressure to the airway of a patient 2 . The ventilator device 1 may also comprise at least one pressure sensor and / or flow sensor 4a to 4c for obtai...

Abstract

The present disclosure relates to a method for controlling a ventilator arrangement. The method might be suitable for maintaining or achieving a desired end expiratory lung volume, EELV, of a subjectwhen an external manoeuvre is performed on the subject ventilated by the ventilator arrangement. The ventilator arrangement applies a set positive end-expiratory pressure, PEEP, level for performing the ventilation.

Description

technical field [0001] The present disclosure relates to ventilator devices and methods for controlling ventilator devices. The present disclosure also relates to computer-readable media and to computer program products. Background technique [0002] When using thoracic forces or any other external manipulation affecting the abdomen, it is important to maintain the subject's end-expiratory lung volume. An example could be changing the position of an object from a horizontal position to a so-called Trendelenburg position. In this case, the weight of the abdomen will put additional pressure on the diaphragm and thus the lungs so that lung volumes may be affected. Another example could be the use of CO during laparoscopic surgery 2 Compression of the abdomen, which may be due to CO 2 Exposing the lungs to extra pressure from the abdomen affects lung volume. During external manipulations such as those described above, for example during preparation for surgery, a subject ma...
