What is the pressure setting when using an autoclave for steam sterilization?

The pressure setting of 15 psi for steam sterilization in an autoclave is standard because it achieves the required temperature of at least 121 degrees Celsius (250 degrees Fahrenheit) necessary to effectively sterilize equipment and materials. At this pressure, steam can penetrate packaging and surfaces efficiently, ensuring that microorganisms, including bacteria and spores, are effectively destroyed during the sterilization cycle.

Using pressures lower than 15 psi may not reach the required temperature, which could compromise the sterilization process, leading to potential healthcare-associated infections. Conversely, higher pressures such as 20 psi or 25 psi are unnecessary for standard sterilization and can lead to equipment damage or an increased risk of device malfunction. Thus, 15 psi is recognized as the optimal setting for achieving effective steam sterilization.
