Which is considered the best method for checking whether instrument packs are being sterilized when autoclaved? What are the CDC recommendations for each type? Chemical: a. b. Biologic 2. The medical assistant is responsible for making sure no problems occur with autoclave procedures. Describe what could be causing the following problems and how they could be prevented. Damp autoclave paper: a. b. Corroded instruments:

Answer 1

Chemical indicators ir - Monitor one or more of requirements - time, temp and sterilant - can be external and internal - Gives instant results. - Indicates proper conditions for sterilization were present. External Chemical indleator - Process indicator - Distinguishes processed -labels pack. Internal indicatori - Inside each package tray cor) container. from un processed medical devices - Paper strips feards - secures pack - Validates sterilant pin penetration. - can measure all process parameters. - Detects incorrect packaging. & chemical indicator - Incorrect loading. is the best method to check - Malfunction of sterilizer. packages being - Easy to retrieve and read. Sterilized in autodar" Advantages:

Biological indicators: confirm the ability of sterilization process to kill microbeal spores. - large number of sporer - Integrates all parameters of sterilization process - most critical test and needs daily monitoring - Steam steringers, ethylene onide sterilizers Bowie- dick type tests. Recommendations: Recommendations chemical indicator - Daily Bowie dick type test - Eack package, External tray, container. Internal Biological indicator. Daily, every load é implantable device. steam | flash - Every load Ethylene oxide

Deep autoclave paper is a sign that something is wrong with equipment cor) procere cor your building utilines and can lead to de contaminating your sterilized load. It is contamination issue since excessive moisture can act as a pathway for microb may occur due to operator error who are not trai bes: value This too much properly happens because an operation has either loaded material (think density, selected wrong sterilization cycle Los) have improperly handled the boad in some way prior to plaung it in Steringer. Then dont overpack the auto clare, ensure there is plenty of space for steam to travel and verify the correct cycle is selected with proper amount of dry time. Component failure is another cause. Then Check all steam traps, valves, vacuum systems, Chamber drain itralnere etc.

Gorroded 26) Gorroded autoclares .. it is not exhibit normal for an auto indeed such appaling conditions as shown after only 5 years as most autoclares are made of stainless steel that should not corrode. However, stainless steel is susceptible to chlorine attack that cause corrode quickly. It is suspected that the main cause of corrosion was use of tap water (which id chlorinated). Users of autoclares are strongly advised to use distilled water for operation of their autoclares to prevent deterioration that could lead to catastrophic failure of auto clare x OX - ox
