16
Q

HLD

A

High Level Disinfection

17
Q

What has the same HLD technique as an intra cavity examination?

A

If patients are on isolation precautions

18
Q

How are regular patient equipment cleaned?

A

At the discretion of the sonographer

- depends on how dirty the patient is

19
Q

What is proper cleaning of the probe necessary to ensure?

A

The disinfection is successful

20
Q

What are sani cloth plus wipes?

A

Is a wipe commonly used as it kills the most bacteria while maintain the integrity of the inner workings of the transducer

21
Q

What do sani cloth plus kill? (10)

A
  1. E. coli
  2. MRSA
  3. TB
  4. Pseudomonas
  5. Staph aureus
  6. Salmonella
  7. VRE
  8. Herpes simplex
  9. Influenza A
  10. RSV
22
Q

What are 5 problems in the ultrasound department?

A
  1. Time
  2. Space
  3. Training
  4. Knowledge
  5. Clear identifiers
23
Q

How is time a problem in the ultrasound department? (2)

A
  1. Sometimes not enough time to do everything properly
    - time is crunched
  2. Takes time to clean in between patients
    - affects the workflow
24
Q

How is space a problem in the ultrasound department?

A

The rooms are normally relatively small

25
Q

How is training a problem in the ultrasound department?

A

Not the best training for new devices or how to clean the machines

26
Q

How is knowledge a problem in the ultrasound department?

A

Ultrasound is constantly changing so we need to stay on top of things
- on our own time we need to complete a certain amount of credits each year

27
Q

Why has the automated HLD become the next solution in many hospitals/clinics?

A

For reasons of patient safety and staff compliance

28
Q

What widely varies among sonographers, even at the same institution?

A

The soaking practices for manual disinfections

29
Q

How long can manual reprocessing take?

A

20 minutes to complete
