health care facilities. - ✔✔AAMI
✔✔All channels should be purged with filtered medical-grade air at the correct psi (as
per IFU), and that "before storage, the channel of the HLD endoscope should be dry to
help prevent bacterial growth and formation of biofilm. T/F - ✔✔True, According to
ANSI/AAMI ST-91.

cleaning efficacy. - ✔✔1. Establish a benchmark - a level of cleaning that can be
achieved consistently using specific soil markers.
2. Using rapid, easy-to-perform methods that reliably demonstrate that the cleaning
benchmarks have been achieved.
✔✔What are some cleaning verification test that can be used with flexible endoscopes.
- ✔✔-ATP tests

leak test to save time
2. Not following the endoscope IFU
3. Failure to prepare endoscope for immersion
4. Immersing endoscope in water that contain chemical solution
5. Not fully submerging the endoscope
6. Coiling the endoscope too tightly
7. Failure to fully angulate the distal tip
8. Failure to leak test for the required amount of time.
✔✔During point of use cleaning, technicians should flush the auxiliary water channel
and then detach the endoscope from the light source and suction pump. T/F - ✔✔True.
✔✔What are some common errors in point-of-use cleaning and handling? - ✔✔-Failure
to understand its importance.
