With Trendelenburg's position,the entire bed frame is tilted,with the head of the bed down.This position facilitates postural drainage and facilitates venous return in patients with poor peripheral perfusion.
In Fowler's position,the head of the bed is raised to an angle of 45 to 90 degrees or more.It is preferred while patient eats,is used during nasogastric tube insertion and nasotracheal suction,and promotes lung expansion.In reverse Trendelenburg's position,the entire bed frame is tilted,with the foot of the bed down.It is used infrequently,promotes gastric emptying,and prevents esophageal reflux.In semi-Fowler's position,the head of the bed is raised approximately 30 to 45 degrees.This promotes lung expansion and relieves strain on abdominal muscles.
