- Study Design
- Not specified
- Primary Outcome Measures
Name Time Method 1. To identify patients in which the cardiac performance is reduced with increasing therapy pressure<br>2. To identify patients in which the cardiac Performance is enhanced with increasing therapy pressure<br>3. To identify patients in which increasing pressure does not affect hemodynamic parameters at all
- Secondary Outcome Measures
Name Time Method 1. To identify patients in which the cardiac performance is reduced with increasing therapy pressure beneath the lower level of the nomal value range <br>2. To identify patients in which the cardiac Performance is enhanced with increasing therapy pressure and raises from critical hemdonyamic values beneath the lower Level of the normal value range into the normal value range<br>3. To identify patients in which hemodynamic values are always beneath the lower level of normal value range indepedend from the therapy pressure value
