CER Automated Endoscope Reprocessors

Question 1

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

Accepted Answer

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

Answer

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

Question 2

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

Accepted Answer

Manual cleaning and leak testing

Answer

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.

Question 3

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

Accepted Answer

ANSI/AAMI ST91

Answer

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

Question 4

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

Accepted Answer

Attaching all channel connectors according to the manufacturer's IFU

Answer

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

Question 5

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

Accepted Answer

Repeat the full reprocessing cycle from manual cleaning

Answer

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