Overview
The following information provides safe cleaning protocols for the Automated Audiology Clinical Extender (AACE).
For best practices on environmental cleaning in healthcare facilities always consult the latest literature from the Centers for Disease Control and Prevention (CDC.gov) and the United States Environmental Protection Agency (EPA.gov) for a list of registered cleaning agents.
CDC Classification for Risk of Infection
These procedures reference the classification scheme found in the Centers for Disease Control and Prevention (CDC.gov), Guidelines for Disinfection and Sterilization in Healthcare Facilities, 2008. In order to stratify the relative degree of risk for infection when utilizing the individual device components, the procedures are categorized into three levels. The categories and their basic definitions are as follows:
- Critical: Critical items confer a high risk for infection if they are contaminated with any microorganism. Thus, objects that enter sterile tissue or the vascular system must be sterile because any microbial contamination could transmit disease. This category includes surgical instruments, cardiac and urinary catheters, implants, and ultrasound probes used in sterile body cavities. Most of the items in this category should be purchased as sterile or be sterilized with steam if possible. Heat-sensitive objects can be treated with EtO, hydrogen peroxide gas plasma; or if other methods are unsuitable, by liquid chemical sterilants.
- Semi-critical: Semi-critical items contact mucous membranes or nonintact skin. This category includes respiratory therapy and anesthesia equipment, some endoscopes, laryngoscope blades 24, esophageal manometry probes, cystoscopes 25, anorectal manometry catheters, and diaphragm fitting rings. These medical devices should be free from all microorganisms; however, small numbers of bacterial spores are permissible. Intact mucous membranes, such as those of the lungs and the gastrointestinal tract, generally are resistant to infection by common bacterial spores but susceptible to other organisms, such as bacteria, mycobacteria, and viruses. Semi-critical items minimally require high-level disinfection using chemical disinfectants.
- Non-critical: Non-critical items are those that come in contact with intact skin but not mucous membranes. Intact skin acts as an effective barrier to most microorganisms; therefore, the sterility of items coming in contact with intact skin is "not critical."
Cleaning Frequency
The following table indicates that the CDC Risk Classification assigned to a product determines its Cleaning Frequency.
Cleaning Frequency
| CDC Risk Classification | Example Items | Cleaning Frequency |
Critical | Objects that enter sterile tissue or the vascular system such as surgical instruments, cardiac and urinary catheters, implants, and ultrasound probes used in sterile body cavities. | Sterilize after each use. |
Semi-Critical | Devices that use a disposable barrier that comes in contact with mucous membranes or nonintact skin. | Disinfect after each use. |
| Disposable one touch collars, speculums, tips, covers, and all other items that are classified as disposable on their packaging. | Dispose after each use. | |
Non-Critical | Devices and surfaces that come in contact with intact skin but not mucous membranes. | Disinfect weekly or when contaminated. |
Cleaning Precautions
- NEVER use solvents or flammable solutions to clean electronic devices.
- NEVER spray any liquids directly on or immerse any components in water or cleaning solutions; apply any liquids to a clean cloth and then use the cloth to clean the component. This will prevent liquids from seeping into the device via buttons or other permeable access points.
- ALWAYS unplug the electronic devices when cleaning with liquids or damp cloth.
- ALWAYS unplug electronic devices from their power source before cleaning the buttons, dials, switches, keyboard, mouse, or air vents.
- ALWAYS Disconnect keyboards before cleaning them.
- ALWAYS Wear safety glasses equipped with side shields when cleaning the keyboard.
- ALWAYS use approved disinfecting wipes and/or a soft cloth, lightly moistened with the approved cleaning solutions per CDC guidelines where applicable.
- NEVER use any abrasive cleaners or volatile solvents.
- NEVER use any alcohol, ammonia, or abrasive products on screens or monitors to avoid damage or cloudy appearance.
- NEVER excessively wipe a camera lens as this may result in fogging.
- ALWAYS consult CDC guidelines and product manuals, if in doubt.
Procedure
The following table details the cleaning guidelines for the Automated Audiology Clinical Extender (AACE).
AACE Cleaning Guidelines
| Component | Procedure | CDC Classification |
Device body, buttons, and cords | Gently wipe all parts of the outer surfaces of the equipment with a soft cloth moistened with a small amount of mild detergent. Critical Note: Avoid allowing liquids to seep into the device via buttons or other permeable access points. |
Non-critical |
Monitor screen(s) |
Critical Note: Do not scrape or tap the screen(s) with any sharp objects.
|
Non-critical |
Headphones/Transducers | Use of a non-alcohol based disinfectant such as those with the active ingredient quaternary ammonia compound or a hydrogen peroxide based cleaner such as Oxivir Disinfectant Wipes to clean the ear cushions and headset. Critical Note: Avoid allowing liquids to seep into the device via buttons or other permeable access points. |
Semi-critical |
Keyboard | Gently wipe the keyboard with a disinfecting wipe and/ or soft cloth, lightly moistened with a CDC approved cleaning solution. |
Non-critical |
Camera body | Gently wipe the camera with a disinfecting wipe and/ or soft cloth, lightly moistened with a CDC approved cleaning solution. |
Non-critical |
Camera heads and lens | Gently wipe all parts of the outer surfaces of the component with an isopropyl alcohol wipe. When dry, if the lens forms spots, wipe the lens areas with a lens cloth or lens wipe to remove the spots. Critical Note: Do not use disinfectant chemical wipes such as CaviWipes or Optim Wipes as they may damage the lens. |
Semi-critical |
