Quaternary Ammonium, Alcohols, Phenolic, Chlorines, Iodophors Discuss Characteristics Of Quats Non-Sporicidal, Must Remain Wet For 6 - 10 Minutes Discuss Characteristics Of Alcohols Non-Sporicidal, 5 Minute Wet-Contact Time Discuss Characteristics Of Phenolics Non- Sporicidal Discuss Characteristics Of Chlorine Member Of The Halogen Family, Non-Sporicidal, 2.5 Minute Wet Contact Time, 1:10 Dilution Of 5.25% Suggested For Use By The Cdc Process By Which Gluteraldehyde Kills Microbes Alkylation Name The High Level Disinfectants
Glutaraldehyde, Orthodox-Pthalaldehyde, Hydrogen Peroxide, Paracetic Acid Discuss Characteristics Of Glutaraldehyde Kills Bacteria Within 2 Minutes; For Sterilization, Soak Time Is 6 - 10 Hours; It Becomes Unstable After 14 Days Discuss Characteristics Of Opa Has A 14 Day Reuse Life, Can Be Discarded Down The Drain, Does Not Have A Sterilants Label Claim Discuss Characteristics Of Hydrogen Peroxide As An Hld. Can Be Used As A Sterilant At The Right Concentrations, Kills Bactria And Viruses Discuss Characteristics Of Paracetic Acid Broad Spectrum Hld, May Be Used As Sterilant In The Appropriate Aer, Achieves Hld In 5 Minutes What Is The Appropriate Time/Temperature Range For A Pasteurizer? 150 - 170 Degrees F For 30 Minutes What Is The Appropriate Temperature For The Assembly Area? 68 - 73 Degrees F What Is The Appropriate Humidity For The Assembly Area? 30 - 60% Class 5 Integrator Indicator Designed To React To All Critical Parameters And To Be Equivalent To Or Exceed Performance Requirements, Over A Specified Range Of Sterilization Cycles
What Is The Recommended Lighting For Sterile Storage Area? 200 - 500 Lux How Far Should Bottoms Sterile Storage Shelf Be From The Ground? 8 - 10 Inches How Far Away From The Ceiling Should Sterile Items Be Stored? At Least 18 Inches Fifo Ensures That Oldest Items Are Used First. Place Newest Item On The Left And Oldest On The Right. Pull Items From The Right. 4 Number Of Air Exchanges Required In The Sterile Storage Area. Gravity And Dynamic Air Removal These Sterilization Methods Have Commercially-Prepared Process Challenge Devices That Should Be Used At Least Weekly, But Preferably On A Daily Basis. Iuss, Tabletop Steam Sterilizers, Eto, Hydrogen Peroxide, And Ozone Bis Are The Acceptable Means For Providing Quality Assurance Monitoring For These Sterilization Methods. Leak Test This Test Should Be Performed At Least Weekly In An Empty Sterilization Chamber. Six Sigma A Quality Assurance Process That Focuses On Developing And Delivering Near-Perfect Products And Services,Strives To Eliminate Variations, Focuses On Process Improvement. Two Methods Used Are Dmadv And Dmaic.
Lean A Quality Process That Focuses On Eliminating Waste In The Production Of Products. Dmadv Define, Measure, Analyze, Design, Verify Process That Is Used To Develop New Processes. Dmaic Define, Measure, Analyze, Improve, Control Procedure To Monitor And Improve Existing Processes. Magnet Status An Award Given By The American Nurses Credentialing Center To Hospitals That Satisfy Factors That Measure The Strength And Quality Of Nursing Care. Iso An International Standard Used By Participating Organizations To Help Ensure That Quality Services And Products Are Consistently Delivered. Hcahps Standardized Survey Tool That Measures The Patient's Perception Of Their Experience During Their Hospital Stay. Failure Mode And Effect Analysis (Fmea) A Process Designed To Predict The Adverse Outcomes Of Various Human And Machine Failures To Prevent Future Adverse Outcomes. Root Cause Analysis (Rca) A Process That "Looks Backward" At An Event To Help Prevent Its Future Reoccurrence. Quality Assurance A Comprehensive And Measured Effort To Provide Total Quality. Also A Technical, Statistical Sampling Method That Measures Production Quality. Total Quality Improvement (Tqi)
