What device is used for pressure steam sterilization?

• A. Autoclave
• B. Incinerator
• C. Oven
• D. Disinfector

Answer: (A)

The autoclave is the device specifically designed for pressure steam sterilization. It operates by using steam under pressure to exceed the normal boiling point of water, which allows for the effective elimination of all microorganisms, including bacterial spores. The combination of high temperature and pressure achieves sterilization through denaturation of proteins and disruption of cell membranes. This method is the gold standard for sterilizing surgical instruments and other heat-resistant medical devices, ensuring that they are safe for use in procedures. The autoclave's effectiveness is often verified through biological indicators, which further solidifies its role in infection control within healthcare settings. Other options, such as incinerators, ovens, and disinfectors, serve different purposes, such as waste disposal, general drying or heating, and surface or instrument cleaning, but none provide the same reliable steam sterilization needed for surgical instruments.
