What does an autoclave use, along with pressure, to achieve sterilization?

1. Gas

2. Steam

3. Boiling water

4. Chemicals

The correct answer is: Steam

An autoclave uses steam in conjunction with pressure to achieve sterilization. The process involves the introduction of steam into a sealed chamber, which creates a high-pressure environment. This combination of heat and pressure effectively destroys all forms of microbial life, including bacteria, viruses, spores, and fungi. Steam's ability to transfer heat efficiently allows the autoclave to reach the high temperatures needed for sterilization far more quickly than dry heat methods. The moist heat produced by the steam penetrates materials more effectively, ensuring thorough sterilization of instruments, tools, and other items. This method is widely used in various settings, including medical, dental, and cosmetic environments, where maintaining a sterile field is crucial for safety and hygiene. While other methods, such as using gas, boiling water, or chemicals, may be utilized for sterilization, they do not provide the same level of efficacy or are not suitable for all types of materials handled in a nail technician's practice. Hence, steam combined with pressure in an autoclave remains a standard and reliable practice for ensuring sterility.
