無菌技術（Sterile Technique）要求在操作過程中，所有無菌物品必須保持在視線範圍內，且位置不得低於腰部（或無菌台平面）。這是因為人體腰部以下區域在視覺監控上較困難，且容易因碰撞、衣物接觸而造成污染。任何低於腰部或超出視野範圍的無菌物品，在臨床判斷上均應視為已污染，必須重新執行無菌操作以確保病人安全。
Anything below the waist is considered contaminated because it is outside the nurse's direct line of sight and prone to accidental contact. Therefore, keeping the sterile field below waist level constitutes a break in sterile technique.
