無菌技術（Sterile Technique）的核心在於維持無菌物品與無菌區域的完整性，避免微生物污染。維持無菌區域時，必須確保物品始終在視線範圍內，且位置高於腰部（或無菌作業台面），因為低於腰部或視線範圍外的物品，視為已被污染。此外，無菌包裝的邊緣一英吋（約 2.5 公分）區域被視為受污染邊緣（Contaminated Border）。
Proper sterile technique requires keeping sterile items and fields at or above waist level to prevent contamination from lower areas. Items held below the waist or outside the nurse's direct line of sight are considered unsterile. Additionally, the one-inch border around a sterile package is regarded as contaminated, so items must be placed well within the central area.
