|Official Title:||Bronchoscopy and Electric Impedance Tomography to Investigate the Influence of Bronchoscopy on Pulmonary Regional Ventilation Measurements by Electric Impedance Tomography (EIT)|
|Study Start Date :||January 2011|

|Estimated Study Completion Date :||April 2011|
Patients who routinely undergo bronchoscopy will be measured by EIT directly before, directly after and 10, 30, 60 minutes after bronchoscopy with a rubber belt which is placed around their chest. The EIT measurements will take 1-2 minutes; the total examination will last 1.5 hours.
Device: Electrical Impedance Tomography (EIT)
EIT measurements of 1-2 minutes are performed in patients who routinely undergo bronchoscopy (during 1.5 hours) before, directly after and 10, 30, 60 minutes after bronchoscopy. Therefore the rubber belt including 16 integrated electrographic electrodes is placed around the patient´s chest and connected with an EIT device. EIT data are generated by application of a small alternating current of 5mA and 50kHz and are stored and analyzed offline on a personal computer. Pseudonomyzed EIT data are evaluated descriptively.
- Comparison of the change in lung impedance due to ventilation before and after bronchoscopy by EIT measurements [ Time Frame: Single Measurement of 1.5 hours ]It will be investigated if there are changes in lung impedance due to changes in ventilation before, directly after and 10, 30, 60 minutes after bronchoscopy in order to investigate their regional distribution and to generate ideas how the ventilation could be optimized to improve recruitment of the patient´s treatment
