Safety Standards
The purpose of safety checks is to verify patient and operator safety while using the product. A
typical check is to measure the amount of leakage current that could pass through a patient/
operator via contact with the equipment enclosure, EKG electrodes or transducers.

Image Quality Checks
The objective of image quality checks is to measure image attributes to ACR and/or AIUM direction
in order to assure performance and compare results to previous images for degradation. These
measurements are then used to determine if and when further image quality adjustments are
needed.
NOTE:
and coded appropriately (not PM service).
Adequate cleaning and disinfection is necessary to prevent disease transmission.
Possible risk of infection. Do not handle soiled or contaminated probes and other
components that could have been in contact with a patient. It is the operator or
sonographer's obligation to clean and disinfect all parts that come in contact with
the patient. Check with the operator on the conditions and follow appropriate
cleaning and disinfection procedures before handling the equipment.

Probe Cleaning
Before cleaning the probes, refer to the Operator's Manuals for cleaning and disinfecting instructions.
Failure to follow these instruction will likely result in damage to probe materials and performance.
•
To remove coupling gel from a probe, wipe the lens with a soft cloth, warm water and mild soap.
•
To clean other surfaces use warm water and mild soap with a soft sponge, gauze or cloth.
•
Never use detergents or abrasive cleaners unless specified.
•
Probe damage will result if scan gels or lotions other then what is specified by the OEM are used.
•
Scanning gels or lotions containing mineral oil or lanolin are known to cause un-repairable damage.
•
Assure that probes are never soaked or saturated with solutions containing alcohol or hydrogen
peroxide.
•
Prior to every QA procedure,inspect each probe thoroughly for damage or degradation to the housing,
cable, strain relief, lens and seal. Never use or permit a probe with damage or defects to remain in service
when patient safety is questioned.

Disinfection and Cold Sterilization
Perform the probe cleaning instructions before following the disinfecting and sterilization
procedures. In general:
•
Properly immerse the probe in the OEM specified germicide or disinfecting solution. Always
follow instructions for use with germicide manufacturer's direction on concentration, time of
contact, and disposal.
•
Thoroughly rinse all residue from the probe with sterile distilled water after removal from the
germicide.
