無菌技術（Sterile Technique）要求在執行侵入性或傷口處置時，嚴格維持無菌區（Sterile Field）。關鍵原則包含：無菌物品僅能接觸無菌物品、無菌區邊緣 1 吋（2.5 公分）被視為污染區、所有無菌物品必須維持在腰部以上視野範圍內，且絕對禁止跨越無菌區，因為跨越動作會導致空氣中的微粒落入無菌範圍。
To maintain sterile technique, the nurse must keep sterile objects above waist level and within constant view to prevent accidental contamination. Opening the sterile package away from the body minimizes the risk of dropping contaminants onto the sterile field. The one-inch border of the sterile field is considered unsterile, and reaching over the field should be avoided to prevent shedding particles.
