In this study, the sixty mechanically ventilated class I obese patients were divided into two equal groups A and B. group A received RTP position + PEEP protocol, while group B underwent RTP position protocol only. The results showed that the group A protocol has positive effects on the improvement of respiratory mechanics by significant increase the arterial oxygen partial pressure (PaO2) in mmHg to fractional inspired oxygen (FiO2), (PaO2/FiO2 ratio), partial pressure of carbon dioxide (PaCO2), and static compliance (Cstat) parameters. Moreover, a significant decrease in hemodynamics of BP& MAP was measured. While the results of the group B protocol demonstrated a non-significant increase in the PaO2/FiO2 ratio, PaCO2, and Cstat. Besides, non-significant decreases in hemodynamics of blood pressure (BP) & mean arterial blood pressure (MAP) were recorded.
Objective To investigate the effect of the positive end-expiratory pressure (PEEP) titration maneuver with Reverse Trendelenburg Position (RTP) on the respiratory and hemodynamic parameters of mechanically ventilated obese patients.
Design Randomized, control trial. Participants Thirty mechanically ventilated obese patients were randomized equally as a group A to receive Reverse Trendelenburg Position (RTP) + Positive End Expiratory Pressure (PEEP) titration, and group (B): receive Reverse Trendelenburg Position (RTP).
Intervention After post-operative bariatric surgeries, the sixty mechanically ventilated obese patients immediately receive a PEEP and RTP once before the weaning through the ventilator of the operation to evaluate the response of arterial blood gases before admission to the intensive care unit ICU room.
Outcomes The primary outcomes included the respiratory parameters (PaO2/FiO2 ratio, PaCO2, Cstat), and the secondary outcomes included the hemodynamics parameters (systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial blood pressure (MAP)).

| Positive End Expiatory Pressure + Reverse Trendelenburg Position | Experimental | Group A received the procedures of the physiotherapy part by applying proper positioning for better oxygenation and ventilation (Reverse Trendelenburg Position), which is the patient laid supine with the head up 30 degrees higher than the feet & received the recruitment maneuver (RM) by Positive End Expiratory Pressure (PEEP) titration |
|
| Reverse Trendelenburg Position | Active Comparator | Group B received only the procedures of the physiotherapy part at the 3rd phase of operation by applying proper positioning for better oxygenation and ventilation (Reverse Trendelenburg Position), in which the patient laid supine with the head at 15-30 degrees higher than the feet to unload the weight of intra-abdominal contents from the diaphragm, this position:
