Final answer:
Factors affecting steam sterilization include time, temperature, and pressure, while the type of microorganisms present influences the choice of sterilization conditions but isn't listed as a direct factor. An antiseptic is used on tissues for microbial control, and filtration is a non-lethal method for removing microbes. Thermal death time is the duration needed to kill all microbes in a sample at a set temperature.
Step-by-step explanation:
In the context of steam sterilization, all the following factors are known to affect the process: Time, Temperature, Pressure, but the type of microorganisms present is not explicitly listed as one of these factors. Generally, sterilization parameters are designed to eliminate all microorganisms, medically relevant or not. However, the type of microorganisms present does indeed influence the choice of sterilization conditions, as some microorganisms are more resistant to sterilization than others, which can alter the needed duration, temperature, or pressure to achieve sterility.
Antiseptic is the substance suitable for use on living tissues to control microbial presence and prevent infection. In contrast, filtration is a method used for microbial control that does not kill or inhibit microbial growth but instead physically removes microbes from samples. Thermal death time (TDT) describes the time required to kill all of the microbes within a sample at a given temperature, and it is a critical parameter in designing sterilization protocols that involve the application of heat.
