The purpose

Background: Positive end expiratory pressure (PEEP) at the time of induction increases oxygenation by preventing lung atelectasis. However, PEEP may not prove beneficial in all cases. Factors affecting the action of PEEP have not been elucidated well and remain controversial. Pulmonary vasculature has direct bearing on the action of PEEP as has been proven in previous studies. Thus this study was planned to evaluate the action of PEEP on the basis of pulmonary artery systolic pressure (PASP) which is non invasive and easily measured by trans-thoracic echocardiography. Methodology: This Randomized prospective study comprised of 70 morbidly obese patients, ASA grade II or III, aged 20-65 years with BMI > 40kg/m2, scheduled for elective laparoscopic bariatric surgery. Ten patients had to be excluded. Thus a total of 60 patients participated in the study. Thirty patients received no PEEP at the time of induction while other 30 patients were given a PEEP of 10cm of H2O. Serial ABG samples were taken pre operatively, at the time of intubation, 5 min after intubation and 10 min after intubation. Patients were then divided into four groups on the basis of PASP value of ≤ 30 mm Hg with and without PEEP or > 30 mm Hg
