Comparison of Two Mechanical Ventilation Modes on Oxygenisation

Bagcilar Training and Research Hospital30 enrolled

Overview

Comparison the effect of two different mechanical ventilation modes on tissue oxygenization.

Aim of the study is to evaluate and compare the effects of two different mechanical ventilation modes as Volume Controlled Mechanical Ventilation (VCV) and Pressure Controlled Mechanical Ventilation (PCV) on non invasive tissue oxygenization levels of patients who scheduled for bariatric surgery.
