1

Why do we clean transducers?

To prevent nosocomical infections

2

What are nosocomical infections?

Infections you pick up at a hospital

3

How many types of transducer care is there?

3

4

What are the 3 types of transducer care?

1. Critical
2. Semi-critical
3. Non-critical

5

Critical transducer care

Device enters otherwise sterile tissue

6

What is an example of critical transducer care?

Intraoperative applications

7

What is the level of disinfection for critical transducer care?

Sterilization

8

Semi-critical transducer care

Device contacts mucous membranes

9

What is an example of semi-critical transducer care?

Endocavity applications

10

What is the level of disinfection for semi-critical transducer care?

High

11

Non-critical transducer care

Device contacts intact skin

12

What is the level of disinfection for non-critical transducer care?

Intermediate or low

13

What are 5 examples of transducer care?

1. Store in clean areas in holders/transducer racks
2. Keep the cords off of the floor
3. Wipe the probe and the cord between each patient
4. Use carrying cases for transport
5. Use sterilization wipes/solution

14

What kind of sterilization wipes should you not use? (4)

1. Bleach
2. Ammonia
3. Alcohol base solutions
4. Sprays

15

Why should you not use bleach/spray products?

Easy to inhale

16

What kind of sterilization wipes should you use? (3)

1. 5% hydrogen peroxide
2. CAVI-wipes ***
3. Preempt

17

What kind of sterilization should you use for invasive transducers?

Let the transducer soak in solution for x minutes
- CIDEX
- Recert

18

What are 4 examples of an invasive transducer?

1. Transvaginal transducer
2. Transrectal transducer
3. Transesophageal transducer
4. Catheter mounted transducer

19

Why do we use invasive transducers?

It gets us much closer to the tissue so we get a higher resolution

20

Why are we able to use high frequency without worrying about attenuation with invasive transducers?

Because since it is invasive you are lowering the distance therefore you are lowing the attenuation

21

What are side lobes?

Additional beams of lower intensity on with side of the transducer

22

What are side lobes considered?

Artifacts
