What is the purpose of an autoclave?
Autoclaves are used in laboratories to sterilize equipment, instruments, and infectious waste. No one who has not received training in autoclave procedure or is not working under the supervision of an experienced autoclave worker should attempt to operate the autoclave.
When should sterile gloves be worn?
They are required for any invasive procedure and when contact with any sterile site, tissue, or body cavity is expected (PIDAC, 2012). Sterile gloves help prevent surgical site infections and reduce the risk of exposure to blood and body fluid pathogens for the health care worker.
What is the fastest method of sterilization?
Filtration is the quickest way to sterilize solutions without heating. This method involves filtering with a pore size that is too small for microbes to pass through. Generally filters with a pore diameter of 0.2 um are used for the removal of bacteria.
What does an autoclave kill?
An autoclave is a machine that uses steam under pressure to kill harmful bacteria, viruses, fungi, and spores on items that are placed inside a pressure vessel. The items are heated to an appropriate sterilization temperature for a given amount of time.
How many sterilization methods are there?
The sterilization methods series can help you make an informed decision. It includes 12 blog posts and covers 9 different sterilization methods that can be divided into two major categories: heat and non-heat sterilization methods.
What is the best way to ensure your autoclave is working properly?
To be effective, the autoclave must reach and maintain a temperature of 121° C for at least 30 minutes by using saturated steam under at least 15 psi of pressure. Increased cycle time may be necessary depending upon the make-up and volume of the load.
At what temperature is sterilization done?
Specific temperatures must be obtained to ensure the microbicidal activity. The two common steam-sterilizing temperatures are 121°C (250°F) and 132°C (270°F). These temperatures (and other high temperatures)830 must be maintained for a minimal time to kill microorganisms.
Why is it important to eliminate air from the sterilizer prior to the process of sterilization?
Sterilisation overview Saturated steam condensing onto a surface is essential for killing microorganisms that may be present on the material surface. It is important to remove air before steam sterilisation (prevacuum) and to ensure air is not being drawn into the autoclave during the prevacuum process.
What are the types of sterilization?
Other Sterilization Methods
- Ionizing Radiation.
- Dry-Heat Sterilizers.
- Liquid Chemicals.
- Performic Acid.
- Filtration.
- Microwave.
- Glass Bead “Sterilizer”
- Vaporized Hydrogen Peroxide (VHP®)
How effective is Sterilisation?
Female sterilisation is more than 99% effective at preventing pregnancy. You do not have to think about protecting yourself against pregnancy every time you have sex, so it does not interrupt your sex life. It does not affect your hormone levels and you’ll still have periods.
What are 3 types of sterilization?
Three primary methods of medical sterilization occur from high temperature/pressure and chemical processes.
- Plasma Gas Sterilizers.
- Autoclaves.
- Vaporized Hydrogen Peroxide Sterilizers.
What is the working principle of autoclave?
The autoclave works on the principle of moist heat sterilization where steam under pressure is used to sterilize the material present inside the chamber. The high pressure increases the boiling point of water and thus helps achieve a higher temperature for sterilization.
Is Pasteurization a form of sterilization?
People often think sterilization and pasteurization are one and the same thing. This is not true. Sterilization is the process that kills all microorganisms and their spores whereas pasteurization kills only the vegetative form of bacteria and not the spores.
Why is sterile processing important?
Sterile processing technicians are incredibly important in healthcare because sterilization and sanitation are vital to patient outcomes. In other words, sterile processing technicians are important because they minimize the risk of a patient suffering unnecessarily from a preventable infection.
What are the steps of sterilization?
The process is divided in different steps and the details of each one are described below:
- STEP 1: CLEANING.
- STEP 2: RINSE.
- STEP 3: DRYING.
- STEP 4: VISUAL INSPECTION.
- STEP 5: STERILIZATION PACKAGE.
- STEP 6: STERILIZATION.
What is the advantage of autoclave?
Autoclaving provides heat and moisture as the damage factors to destroy organisms. Most organisms can be destroyed in the presence of steam under pressure at 121 oC for a minimum of 15 minutes. The time is measured after the temperature of the material being sterilized reaches 121 o C.
Do autoclaves kill everything?
Proper autoclave treatment will inactivate all resistant bacterial spores in addition to fungi, bacteria, and viruses, but is not expected to eliminate all prions, which vary in their resistance.
How is dry sterilization done?
The dry heat sterilization process is accomplished by conduction; that is where heat is absorbed by the exterior surface of an item and then passed inward to the next layer. Eventually, the entire item reaches the proper temperature needed to achieve sterilization.
What is the first step in sterilization process?
The first step, cleaning and disinfection, is critical because soil must be removed before instruments are ready for further processing, as the presence of soil or organic material on instruments reduces disinfection or sterilization effectiveness .
How do you put on and remove sterile gloves?
Step 4. Put on the first glove
- Take the hand you write with and grasp the glove for your other hand at the folded edge of the cuff.
- Pick up the glove by the folded edge.
- Put your hand inside the glove.
- Pull the glove on.
- Be careful not to touch the outside of the glove.
- Leave the cuff on the glove folded.
How do you learn sterile processing?
How to Become a Sterile Processing Technician
- Choose the Right Sterile Processing Tech Training Program. Schools may call this career by a variety of names, including:
- Enroll in Your Sterile Processing Technician Program.
- Attend Your Program Orientation.
- Begin Your Sterile Processing Technician Training.
- Pass Your CRCST Exam.
Do all culture media need to be sterilized before?
When microbiological media has been made, it still has to be sterilized because of microbial contamination from air, glassware, hands, etc. Within a few hours there will be thousands of bacteria reproducing in the media so it has to be sterilized quickly before the microbes start using the nutrients up.
What is a disadvantage of flash sterilization?
What is a primary disadvantage of flash sterilization? instruments are sterilized while unpackaged, and they are no longer sterile once removed from the sterilizer so cannot be packaged. What is a major advantage of chemical vapor sterilization? it does not rust, dull, or corrode dry metal instruments.
What is the function of autoclave?
Autoclaves operate at high temperature and pressure in order to kill microorganisms and spores. They are used to decontaminate certain biological waste and sterilize media, instruments and lab ware.

What are the 4 methods of sterilization?
Classical sterilization techniques using saturated steam under pressure or hot air are the most reliable and should be used whenever possible. Other sterilization methods include filtration, ionizing radiation (gamma and electron-beam radiation), and gas (ethylene oxide, formaldehyde).
