About this study

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.

Inclusion criteria

  • ASA PS 1-2 obese patients(BMI>30)

Exclusion criteria

  • underlying cardiopulmonary diasease

Treatment and study plan

inverse ratio ventilation

Other

change the I: E ratio 1:2-1:1-2:1

Primary outcomes

  1. Arterial oxygenation (PaO2)

    Time frame: baseline PaO2-2hour after pneumoperitoneum

    sampling for arterial blood from arterial cannular weill be analysed 10 min after anesthetic induction, 20 min after pneurmoperitoneum (PP)with 1:2 of IE ratio, 20 min after after pneurmoperitoneum (PP)with 1:1 of IE ratio, after pneurmoperitoneum (PP)with 2:1 of IE ratio and end of operation
