Abstract
Objective: The aim of this study was to investigate the Response of Arterial Blood Gases to Positive End Expiratory Pressure Titration for Mechanically Ventilated Obese Patients. Methods: sixty mechanically ventilated obese patients undergoing general anesthesia, their age ranged from 40-50 years old, with BMI class I obesity (30-34.9) kg/ m2 and both sexes participated in this study, were enrolled and were selected inside Operation Room (OR) of the surgical department, second floor of Manial in Kasr Al Aini hospital, Cairo, Egypt. The study was conducted from May 2018 to August 2018. They were randomly assigned into two groups equal in number. group (A): thirty participants that had received (PEEP titration twice 30 cmH2o for 30 seconds + Reverse Trendlendburg Position RTP for 20 minutes at 3rd& 4th phase of operation) as one shot treatment. group (B): thirty patients who received (Reverse Trendlendburg Position RTP for 20 minute at 3rdphase of operation). The measurement of Pao2/ Fio2 ratio, Paco2 from Arterial Blood Gases(ABGs)&Cstat from mechanical ventilator monitor and blood pressure &Mean Arterial Blood Pressure(MAP) from arterial line and patients vital signs monitor were obtained before and after the procedure
