When validating an AER after installation, which parameter must be confirmed to meet manufacturer specifications?
Answer: Disinfectant contact time and concentration
AER validation requires confirming that disinfectant contact time and concentration meet manufacturer specifications to ensure effective high-level disinfection.
An AER cycle aborts mid-process due to a pressure fault. What is the FIRST action the reprocessing technician should take?
Answer: Remove the endoscope and manually complete high-level disinfection
When an AER cycle aborts, the endoscope should be removed and manually high-level disinfected to ensure it is safe before patient use.
Which water quality standard is most critical for the final rinse phase of an AER cycle?
Answer: Sterile water or water meeting AAMI ST108 standards
AAMI ST108 establishes water quality standards, and the final rinse in an AER must use appropriately treated water to prevent recontamination of the endoscope.
How often should AER filters (e.g., HEPA or water filters) typically be changed according to best practice?
Answer: According to the manufacturer's instructions for use
Filter replacement intervals must follow the AER manufacturer's instructions for use (IFU), as intervals vary by design and water quality.
A biological indicator (BI) test of an AER shows growth after the cycle. What does this indicate?
Answer: The AER cycle may have failed to achieve adequate disinfection
Growth in a BI after an AER cycle indicates the process may not have achieved the required level of microbial kill, necessitating investigation and remediation.
Which component of an AER is specifically designed to flush liquid through endoscope internal channels?
Answer: The channel irrigation manifold or connector ports
The channel irrigation manifold or connector ports of an AER deliver disinfectant and rinse water through all internal channels of the endoscope.
What is the purpose of the drying phase at the end of an AER cycle?
Answer: To remove residual moisture and prevent microbial growth during storage
The drying phase removes residual moisture from channels and surfaces to inhibit microbial growth during storage between uses.
