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)

Conditions

• Ventilator Lung

Interventions

Type	Name	Description
OTHER	Starting with volume controlled ventilation and changing the ventilation mode every 20 minutes	group 1 starts with volume controlled ventilation and we take three consecutive measurements in twenty minutes , after twenty minutes we change the ventilation mode to pressure controlled ventilation after letting washout we take three consecutive measurements at pressure controlled ventilation and we will repeat this protocol during surgery
