Read the first 7 Automated Endoscope Reprocessors flashcards as text

  1. What is the primary purpose of an Automated Endoscope Reprocessor (AER)?

    Answer: To automate the high-level disinfection and rinsing cycle for endoscopes

    AERs automate the high-level disinfection and rinsing process, reducing manual steps and human error in endoscope reprocessing.

  2. Before placing an endoscope into an AER, which step must always be completed first?

    Answer: Manual cleaning and leak testing

    Manual cleaning and leak testing must precede AER use because the machine cannot remove gross bioburden and a leak could allow chemical infiltration into the scope body.

  3. Which document provides the primary guidance for validating AER cycles for endoscope reprocessing in the US?

    Answer: ANSI/AAMI ST91

    ANSI/AAMI ST91 is the primary US standard specifically addressing flexible and semi-rigid endoscope reprocessing, including AER validation requirements.

  4. When connecting an endoscope to an AER, which action is most critical for ensuring effective channel reprocessing?

    Answer: Attaching all channel connectors according to the manufacturer's IFU

    Connecting all channel connectors per the manufacturer's Instructions for Use (IFU) ensures every lumen receives adequate disinfectant flow and rinsing.

  5. What is the recommended action when an AER cycle is interrupted before completion?

    Answer: Repeat the full reprocessing cycle from manual cleaning

    An interrupted AER cycle means the scope cannot be considered adequately reprocessed; the entire reprocessing sequence must be restarted from manual cleaning.

  6. How often should AER water filters typically be replaced?

    Answer: According to the AER manufacturer's recommended schedule in the IFU

    Filter replacement intervals vary by AER model and use volume; the manufacturer's IFU specifies the correct schedule to maintain water quality and machine performance.

  7. Which type of water is recommended for the final rinse step in most AERs to prevent waterborne pathogen contamination?

    Answer: Sterile water or filtered water meeting AAMI quality standards

    Sterile or AAMI-quality filtered water for the final rinse prevents recontamination with waterborne organisms such as Pseudomonas aeruginosa or nontuberculous mycobacteria.
