Superheating can occur - If the steam pressure is too low for the set temperature Wet packs - Wet steam can cause 68-73 degrees - AAMI recommends that the temperature in the sterilization area be: 30%-60% - AAMI recommends that the humidity is the sterilization area be 10 - The recommended ventilation in the sterilization are is—— air exchanges per hour under positive pressure 75-85/10/negative - AAMI recommends that the temperature in the sterilizer access area be —- with — air exchanges per hour and under — pressure Decon, the sterilizer access area, EVS closet - The only 3 areas in SPD that should have negative pressure are: sterility - — is the absence of all forms of microbial life, including bacterial spores One in a million; 10(-6) - An item is considered sterile if there is less than —— chance that a viable microorganism has survived the sterilization process. This is reflected numerically as —- Sterility Assurance Level - SAL= Steam - — kills microorganisms by denature great the protein steam sterilization - — is the most common form of sterilization for items that are heat- and moisture-tolerant saturated steam under pressure, time, and temperature - Three parameters of steam sterilization cycles are Dynamic-air-removal cycles - — are used in prevacuum sterilized and in steam-flush pressure-pulse (SFPP) Prevacuum sterilizers - — remove air by drawing series of vacuums with an injection of steam between each vacuum pull. Bowie-Dick test - Performed daily to detect air leaks or inadequate air removal from prevacuum sterilzers Gravity-displacement cycles - Incoming steam displaces residual air through the drain at the bottom of the sterilizer chamber: Gravity-displacement - Because there is no mechanical air removal in a —, a Bowie-Dick test is not required for — or sterilizers Boiler - In most healthcare facilities, steam is generated inside of a: 60-80psig - The required pressure of steam as it enters the jacket is usually: 28-30 lbs of pressure - For a sterilizer operating at 270 degrees, the sterilizer gauge will show: An insulating jacket - Provides heat inside the chamber to prevent condensation from forming on the chamber walls: Heat-sensing thermometer - The sterilizers - - - is locates in the drain line The drain line - The coldest part of sterilizer is Bottom rack, drain line - All PCDs should be placed on the —, directly over the — On the bottom rack above the drain line - The Bowie-Dick test pack is placed Conditioning, sterilization/exposure/"holding, Exhaust, Drying - The phases of steam sterilization cycles are: Conditioning phase - During this phase, air is removed from the sterilization chamber and steam is injected Sterilization/exposure/holding - In this phase, the exposure temperature is maintained for the prescribed amount of time. Exhausted, Exhaust phase - After the exposure phase, steam is — from the sterilizer through the chamber drain line is this phase: Drying phase - After the steam has been exhausted, the sterilizer goes into the - of the cycle which typically lasts about 30 minutes • 4 minutes @ 270 and 28-30 psi • 3 minutes @ 275 and 38-30 psi - The cycle for wrapped items using Dynamic-air-removal steam is: • 30 minutes @ 350 and 15 psi • 15-20 minutes @ 270 and 27 psi • 10 minutes @ 275 and 30 psi - The cycle for wrapped items using Gravity-displacement steam: BI PCD - To verify that the cycle met the requirements for sterilization, a — should be included in the load (whether or not the load contains implantable devices) Immediate-Use steam sterilization (IUSS) - —- is usually performed when an unplanned event occurs Rigid sterilization container - AORN recommends that IUSS be performed in a IUSS — thAt has been validated and FDA cleared for IUSS cycles Metal items only; no porous or lumened items: 270 or 275 for 3 minutes Metal items with lumens and/or porous items: 270 or 275 for 4 minutes - IUSS cycles for unwrapped items are as follows: (dynamic-air-removal) Metal items only; no porous or lumened items: 270 or 275 for 3 minutes Metal items with lumens and/or porous items: 270 or 275 for 10 minutes - IUSS cycles for unwrapped items are as follows: (gravity-displacement) 1. Cleaning and decontamination 2. Sterilization 3. Storage or return to the sterile field - The 3 critical steps of reprocessing are: 18 minutes @ 274 in a prevacuum steam sterilizer Or 1 hour @ 250 in a gravity- displacement steam sterilizer - The minimum exposure time for processing instruments used on patients with CJD is: Neurosurgical and ophthalmology - Many — and — instrument manufacturers have validated their instruments for prion-contaminated device cycles Patient ID, date instruments were used, procedure performed and surgeons name - A tracking system for patients at risk of CJD should include: Gravity-displacement liquids cycle - Liquids can be processed only in a: Steam sterilization - Heat + moisture = Condensation - Steam sterilization occurs by: Superheating - — occurs when saturated steam at any given temperature is subjected to a higher temperature...this occurs when heat is added to dry steam in the absence of water
