Clinical Trial Summary

for evaluating inverse ratio ventilation of laparoscopic bariatric surgery

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.
