5. Study Description
Brief Summary
for evaluating inverse ratio ventilation of laparoscopic bariatric surgery
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.
