Exclusion criteria

* Currently has a permanent or temporary pacemaker, implantable cardiac device (ICD) or other device emitting electrical energy * a BMI ≥ 50 * tidal volume (VT) ≤ 200 mL * Current uncontrolled body movements such as tics, tremors or seizures, * Current wound dressings or infections on the chest that might interfere with the PulmoVista 500 electrode belt placement * Women of child bearing potential whose pregnancy cannot be excluded based on a pregnancy test or other proven facts. * Allergic to materials used in the electrode belt * Participation of the patient in an interventional trial within the last four weeks before enrollment in this trial * Evidence suggesting that the patient or his legal representative is not likely to follow the trial protocol (e.g. lacking compliance) * Known infectious diseases that require isolation of patient (e.g. MRSA) * Concomitant use of an air anti-decubitus medical mattress with dynamic inflation that cannot be deactivated during EIT measurements

Design outcomes

Primary

MeasureTime frameDescription
Monitoring Capabilities of PulmoVista 500Day 1The cross-correlation between the volume curve of the ventilator and the global impedance curve of PulmoVista 500 was expressed by the cross-correlation coefficient R. The cross-correlation coefficient is a measure to quantify the relationship between the volume curve and the EIT curve. The correlation coefficient R can assume values between \[-1, 1\] to describe the relationship between the two curves, as is usual for a correlation. To calculate the correlation coefficient, a phase shift between the two curves was taken into account, so the cross-correlation between them was calculated. The phase shift or delay occurs when the signal from the fan is transmitted to the PulmoVista500. The cross-correlation coefficient is determined by calculating the correlation coefficient for the curves within a narrow range of Lags(-15 to 15 ) for each pair of curves and using the maximum value as the value of correlation coefficient (therefore it is called cross-correlation coefficient)

Time frame: Day 1

Population: A Intention-to-Treat (ITT) collective was used as analysis population. The intention-to-treat collective comprises all patients for which both, the impedance waveforms and parallel to them volume waveforms have been generated during ventilation,so that the primary endpoint can be evaluated.

Detection of Changes in Regional Ventilation

To assess the capability of PulmoVista 500 to detect changes in regional ventilation by evaluating the cross correlation between impedance waveforms derived from PulmoVista 500 and volume curves derived from ventilator during one-lung-ventilation.

Time frame: Day 1

Population: For this secondary endpoint the cross-correlation between between impedance waveforms derived from PulmoVista 500 and volume curves derived from Ventilator was calculated only for patients which received one-lung-ventilation (OLV).~Therefore no patients from the ICU patients Group were included into the analysis.
