During a surgical procedure, the sterile zone is primarily confined to the table top and waist level. This area is where the surgical instruments, sterile drapes, and sterile surfaces are maintained to ensure that they do not come into contact with non-sterile items and potential contaminants. The table top serves as the primary workspace for the surgical team, while maintaining a sterile field at waist level minimizes the risk of contamination from any non-sterile surfaces or items around the operating room.

The sterile zone is crucial for preventing infection, as any breach in sterility can increase the risk of postoperative complications. Although some aspects of a surgical field may extend above shoulder height or involve other areas of the operating room, the key zones that are consistently monitored and maintained for sterility are the table top and waist level. This understanding reinforces the discipline required in the surgical environment to protect patient health and safety during procedures.
