CBSPD Sterilization - Certification Exam Review

CBSPD Sterilization - Certification Exam Review Steam Using Gravity Displacement: Method of Killing - Denatures microorganism proteins Steam Using Gravity Displacement: Sterilant Used - Combination of steam and ambient air Steam Using Gravity Displacement: How do steam and ambient are sterilize? - Steam displaces the air, and forces it out of the drain vent. Steam then comes in direct contact with items Steam Using Gravity Displacement: Parameters (3) - 1. Time 2. Temperature 3. Pressure Steam Using Gravity Displacement: Common cycle times (3) - 1. 30 min, 250°F, 15 psi 2. 15-25 min, 275°F, 27 psi 3. 10 min, 275°F, 30 psi Steam Using Gravity Displacement: Items that CAN be sterilized - 1. Critical items that are heat and moisture resistant 2. Semi-critical items that are heat and moisture resistant 3. Sharps Containers Steam Using Gravity Displacement: Items that CANNOT be sterilized - Heat and moisture sensitive materials Steam Using Gravity Displacement: Biological Indicator - Geobacillus Stearothermophilus Steam Using Dynamic Air Removal: Method of Killing - Denatures microorganism proteins Steam Using Dynamic Air Removal: Sterilants Used (3) - 1. Combination of steam and ambient air 2. Prevacuum Sterilizers 3. (SFPP) Steam-flush pressure-pulse sterilizers Steam Using Dynamic Air Removal: Parameters (3) - 1. Time 2. Temperature 3. Pressure Steam Using Dynamic Air Removal: Common Cycle Times (2) - 1. 4 min, 270°F, 28-30 psi 2. 3 min, 275°F, 28-30 psi Steam Using Dynamic Air Removal: Items that CAN be sterilized - 1. Critical items that are heat and moisture resistant 2. Semi-critical items that are heat and moisture resistant 3. Sharps Containers Steam Using Dynamic Air Removal: Items that CANNOT be sterilized - Heat and moisture sensitive items Steam Using Dynamic Air Removal: Biological Indicator - Geobacillus Stearothermophilus EO: Method of Killing - Alkylation: interferes with microorganism metabolism EO: Sterilants Used (2) - 1. 100% EO (undiluted) - common 2. EO Mixtures (contains HCFC and CO2) - uncommon EO: Parameters (5) - 1. Time 2. Temperature 3. Pressure 4. Humidity 5. Concentration EO: Common cycle time - 2.5 hours (not including aeration time) EO: Items that CAN be sterilized (3) - 1. Critical items that are heat, pressure, and moisture sensitive 2. Semi-critical items that are heat, pressure, and moisture sensitive 3. Devices with long lumens EO: Items that CANNOT be sterilized - Trays
