Sim's position is characterized by a left side-lying posture where the upper leg is flexed at the hip and knee. This position allows for optimal drainage of fluids from the lungs and is frequently used for patients undergoing certain medical and surgical procedures. It is also comfortable for patients who may need to breathe more easily or require access to the rectal area for examinations or procedures.
