無菌技術（Sterile technique）的目的在於建立並維持無菌區。護理師需確保無菌物品始終在視線範圍內，一旦離開視線即視為污染。無菌區邊緣 2.5 公分（1 英寸）被視為污染邊界，因為邊緣可能接觸到非無菌區域。無菌物品需置於腰部以上，因為低於腰部時視線難以監控。嚴禁跨越無菌區，因為氣流會帶動懸浮微粒落入，破壞無菌狀態。
Maintaining sterile technique requires keeping the sterile field within direct line of vision and holding items above waist level to prevent contamination. The outer one-inch border is considered unsterile, and reaching over the field or allowing items to drop below the waist compromises sterility.
