Inverse Ratio Ventilation on Bariatric Operation
August 30, 2015 updated by: Youn Yi Jo, Gachon University Gil Medical Center
Effects of a Changes in Inspiratory to Expiratory Ratio on Respiratory Mechanics and Oxygenation During Laparosopic Bariatric Surgery
for evaluating inverse ratio ventilation of laparoscopic bariatric surgery
Study Overview
Detailed Description
inverse ratio ventilation had been improve the oxygenation and respiratory mechanics during care of ARDS patients or during general anesthesia.
We hypothized inverse ratio ventilatio could improve the oxygenation and respiratory mechanics on the obese patient also.
