- Should maintain negative pressure to ensure that contaminated air is not exhausted into prep or
other areas. ✔️
- Air must be directly exhausted to the outside.
- Requires 10 air exchanges per hour.
- Clean floors and horizontal work surfaces must be cleaned daily.
- Vents and walls should be routinely cleaned.
- Workflow should flow from clean to dirty areas.
- Floor drains must be treated to inhibit microorganism growth and prevent noxious odors.
Cleaning and Reprocessing of Flexible Endoscopes
2. Challenges:
- Flexible endoscopes are difficult to clean due to their numerous small channels/lumens and lengths
of over 6 feet. ✔️
3. Types of Flexible Endoscopes:
- Include bronchoscopes, duodenoscopes, gastroscopes, enteroscopes, cystoscopes,
nasopharyngoscopes, ureteroscopes, and ultrasound endoscopes. ✔️
4. Reprocessing Requirements:
- Most flexible endoscopes are classified as semi-critical and require high-level disinfection (HLD);
some may be low-temperature sterilized.
- Only trained personnel with verified competencies should reprocess these devices. ✔️
- Follow the manufacturer's instructions carefully. Cleaning is generally done manually and separately
to prevent cross-contamination (e.g., using a 1x detergent bath with a soft cloth). ✔️
, 5. Damage Precautions:
- Automated washers and ultrasonic cleaners can damage flexible endoscopes; therefore, a soft bristle
brush should be used for cleaning.
- Outer surfaces and accessories should be wiped with a cloth moistened with detergent and
thoroughly rinsed. ✔️
AER (Automated Endoscope Reprocessor)
6. Pre-processing:
- Decontamination must be completed before placing endoscopes in an AER.
- Conduct a leak test:
- Submerge in a manual bath for 5-10 minutes.
- Wipe down with a lint-free, soft cloth.
- If lumen channels are present, flush and brush the channels until clean, then rinse and dry.
Steris AER Peracetic Acid
7. Usage Guidelines:
- A diagnostic run may be required in an AER with peracetic acid (PA) before processing actual loads.
- It is designed for immersible items only and should be connected properly to allow liquid to flow
through channels.
- Not all endoscopes are suitable for processing in an AER (e.g., bronchovideoscope) or may lack
internal channels (e.g., nasopharyngoscope).
