Brief Summary in Lay Language

The goal of this study is to examine a method to improve patient ventilation in invasive- and non-invasive ventilation. By measuring respiratory muscle activity during non-invasive ventilation via small electrodes (comparable to those used for ECG) as well as measuring the esophageal pressure using a stomach tube, we can provide important findings about the work of breathing.

Brief Summary in Scientific Language

The Goal of this study is to examine a new, non-invasive tool developed by the Company DRÄGER, which uses surface-electromyography (sEMG) to measure the activity of respiratory muscles at two different sites (parasternal and diaphragmatic). This tool allows measurement of muscle activity without the negative effects of an invasive measurement via an esophageal probe. This new method also potentially allows for mechanical support proportional to the patients individual needs and the improvement of patient- ventilator asynchrony.
Furthermore it provides diagnostic benefits: measuring the diaphragmatic activity could possibly be a early-warning system for prolonged weaning.

Primary Outcome

The Primary Goal is to identify changes in the work of brathing and the sEMG-signal (Surface-electromyography) during invasive ventilation.
For aquiring these information we continously monitor the sEMG of the diaphragm and the intercostal muscles via small electrodes glued to the Skin as well as the esophageal pressure via a esophageal probe.

Secondary Outcome

The influence of the work of breathing on additional data provided by the Ventilator (mouth pressure, gas-flow, FiO2, FeCO2).
