無菌技術（Sterile technique）的目的在於消除所有微生物，防止病原體進入易感部位。維持無菌區（Sterile field）在腰部以上是為了確保護理師能全程監控無菌物品，避免視線死角導致意外污染。一旦無菌物品低於腰部，即視為已污染。臨床上，護理師需確保所有無菌操作皆在視線範圍內進行，並嚴格遵守界線原則以保護病人安全。
Maintaining the sterile field above waist level ensures that the nurse can continuously monitor the area within their line of sight, preventing accidental contamination from unseen sources. Any item that falls below the waist is considered contaminated, so keeping the field elevated is a fundamental principle of sterile technique to protect the client.
