Overview
Brief Summary
Comparison of mechanical powers produced at volume controlled and pressure controlled mechanical ventilation
Detailed Description
The mechanical power created by mechanical ventilation, as a new concept, can enable to evaluate the effect of different components in the lung.Our aim in this study is to calculate mechanical power in different ventilation modes ( pressure controlled and volume controlled ventilation) and to compare them. To calculate the mechanical powers we will use Van der Meijden's mechanical power formula for pressure controlled ventilation and for volume controlled ventilation we will use Gattinoni's mechanical power formula. In the literature we haven't seen any publication comparing the mechanical power of two commonly used ventilation modes (volume controlled and pressure controlled ventilation)

Outcomes
Primary Outcomes
calculation of mechanical power changes in two different ventilation modes
Time Frame: change from at the beginning of surgery till the end of surgery
mechanical power will be calculated using the Van der Meijden's formula for pressure support ventilation and Gattinoni's formula for volume controlled ventilation and two mechanical powers will be compared
Secondary Outcomes
- hospitalisation time(up to 20 days)
- postoperative pulmonary complications(post-operative 7 days)
