Comparison of Two Mechanical Ventilation Modes on Oxygenisation

Comparison of Two Mechanical Ventilation Strategies on Tissue Oxygenization of Patients Undergoing Bariatric Surgery

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.
