WARNING: Some transducer sheaths contain natural rubber latex and talc, which can cause
allergic reactions in some individuals. Refer to 21 CFR 801.437, User labeling for
devices that contain natural rubber.
Some gels and sterilants can cause an allergic reaction on some individuals.
Caution: To avoid damage to the transducer, use only gels recommended by SonoSite.
Using gels other than the one recommended by SonoSite can damage the
transducer and void the warranty. If you have questions about gel compatibility,
contact SonoSite or your local representative.
SonoSite recommends that you clean transducers after each use. See “Cleaning
and disinfecting transducers” on page 41.
WARNING: To prevent contamination, the use of sterile transducer sheaths and sterile
coupling gel is recommended for clinical applications of an invasive or surgical
nature. Do not apply the transducer sheath and gel until you are ready to
perform the procedure.

WARNING: Disinfectants and cleaning methods listed are recommended by SonoSite for
compatibility with product materials, not for biological effectiveness. Refer to the
disinfectant label instructions for guidance on disinfection efficacy and appropriate
clinical uses.
The level of disinfection required for a device is dictated by the type of tissue it will
contact during use. To avoid infection, ensure that the disinfectant type is
appropriate for the equipment. For information, see the disinfectant label
instructions and the recommendations of the Association for Professionals in
Infection Control and Epidemiology (APIC) and the U.S. Food and Drug
Administration (FDA).
To prevent contamination, the use of sterile transducer sheaths and sterile coupling
gel is recommended for clinical applications of an invasive or surgical nature. Do not
apply the transducer sheath and gel until you are ready to perform the procedure.
Caution: Some transducer sheaths contain natural rubber latex and talc, which can cause
allergic reactions in some individuals. Refer to 21 CFR 801.437, User labeling for
devices that contain natural rubber.

WARNING: To avoid electrical shock, before cleaning, disconnect the transducer from the
system.
To avoid injury, always use protective eyewear and gloves when performing
cleaning and disinfecting procedures.
To avoid infection, ensure that the solution expiration date has not passed.
To avoid infection, the level of disinfection required for a transducer is dictated by
the type of tissue it contacts during use. Ensure that the solution strength and
duration of contact are appropriate for the equipment. SonoSite tests products for
compatibility of materials only. SonoSite does not test for biological effectiveness.
For information, see the disinfectant label instructions and the recommendations of
the Association for Professionals in Infection Control and Epidemiology (APIC) and
FDA.
Caution: Transducers must be cleaned after every use. Cleaning transducers is necessary prior
to effective disinfection. Ensure that you follow the manufacturer's instructions
when using disinfectants.
Do not use a surgeon's brush when cleaning transducers. Even the use of soft
brushes can damage a transducer. Use a soft cloth.
Using a non-recommended cleaning or disinfection solution, incorrect solution
strength, or immersing a transducer deeper or for a longer period of time than
recommended can damage or discolor the transducer and void the transducer
warranty.
Do not allow cleaning solution or disinfectant into the transducer connector.
Do not allow disinfectant to contact metal surfaces. Use a soft cloth lightly
dampened in a mild soap or compatible cleaning solution to remove any
disinfectant that remains on metal surfaces.
Attempting to disinfect a transducer or transducer cable using a method other than
the one included here can damage the transducer and void the warranty.

WARNING: To prevent musculoskeletal disorders, follow the guidelines in this section.
Use of an ultrasound system may be linked to musculoskeletal disordersa,b,c.
Use of an ultrasound system is defined as the physical interaction among the
operator, the ultrasound system, and the transducer.
When using an ultrasound system, as with many similar physical activities, you may
experience occasional discomfort in your hands, fingers, arms, shoulders, eyes, back,
or other parts of your body. However, if you experience symptoms such as constant
or recurring discomfort, pain, throbbing, aching, tingling, numbness, burning
sensation, or stiffness, do not ignore these warning signs. Promptly see a qualified
health professional. Symptoms such as these can be linked with musculoskeletal
disorders (MSDs). MSDs can be painful and may result in potentially disabling
injuries to the nerves, muscles, tendons, or other parts of the body. Examples of
MSDs include carpal tunnel syndrome and tendonitis.
While researchers are not able to definitively answer many questions about MSDs,
there is a general agreement that certain factors are associated with their
occurrence including: preexisting medical and physical conditions, overall health,
equipment and body position while doing work, frequency of work, duration of
work, and other physical activities that may facilitate the onset of MSDsd. This
chapter provides guidelines that may help you work more comfortably and may
reduce your risk of MSDse,f.

WARNING: To avoid discomfort or minor risk of patient injury, keep hot surfaces away from the
patient.
Under certain circumstances, the transducer connector and back of the display
enclosure can reach temperatures that exceed EN60601-1 limits for patient contact,
therefore only the operator shall handle the system. This does not include the
transducer face.
To avoid discomfort or minor risk of operator injury when handling the transducer
connector, the system should not be operated for more than 60 minutes
continuously in a live-scan mode (as opposed to freeze or sleep modes).
To avoid the risk of electrical shock or injury, do not open the system enclosures. All
internal adjustments and replacements, except battery replacement, must be made
by a qualified technician.
To avoid the risk of injury, do not operate the system in the presence of flammable
gasses or anesthetics. Explosion can result.
To avoid the risk of electrical shock, use only properly grounded equipment. Shock
hazards exist if the power supply is not properly grounded. Grounding reliability can
only be achieved when equipment is connected to a receptacle marked “Hospital
Only” or “Hospital Grade” or the equivalent. The grounding wire must not be
removed or defeated.
To avoid the risk of electrical shock, when using the system in an environment where
the integrity of the protective earth conductor arrangement is in doubt, operate the
system on battery power only without using the power supply.
To avoid the risk of electrical shock, do not connect the system’s power supply or the
S Stand’s auxiliary mains outlet receptacles to an MPSO or extension cord.
To avoid the risk of electrical shock, before using the transducer, inspect the
transducer face, housing, and cable. Do not use the transducer if the transducer or
cable is damaged.
To avoid the risk of electrical shock, always disconnect the power supply from the
system before cleaning the system.
To avoid the risk of electrical shock, do not use any transducer that has been
immersed beyond the specified cleaning or disinfection level. See Chapter 5,
“Troubleshooting and Maintenance.”
To avoid the risk of electrical shock and fire hazard, inspect the power supply, AC
power cord, and plug on a regular basis. Ensure they are not damaged.
To avoid the risk of electrical shock and fire hazard, the power cord set that connects
the power supply of the ultrasound system or S Series stand to mains power must
only be used with the power supply or S Series stand, and cannot be used to
connect other devices to mains power.
Chapter 6: Safety 55
Safety
WARNING: To avoid the risk of electrical shock, use only accessories and peripherals
recommended by SonoSite, including the power supply. Connection of accessories
and peripherals not recommended by SonoSite could result in electrical shock.
Contact SonoSite or your local representative for a list of accessories and peripherals
available from or recommend by SonoSite.
To avoid the risk of electrical shock, inspect cables and power cords used within the
system on a regular basis for damage.
To avoid the risk of electrical shock to the patient/subject, do not touch the system
battery contacts while simultaneously touching a patient/subject.
To prevent injury to the operator/bystander, the transducer must be removed from
patient contact before the application of a high-voltage defibrillation pulse.
To avoid possible electrical shock or electromagnetic interference, verify proper
operation and compliance with relevant safety standards for all equipment before
clinical use. Connecting additional equipment to the ultrasound system constitutes
configuring a medical system. SonoSite recommends verifying that the system, all
combinations of equipment, and accessories connected to the ultrasound system
comply with JACHO installation requirements and/or safety standards such as
AAMI-ES1, NFPA 99 OR IEC Standard 60601-1-1 and electromagnetic compatibility
standard IEC 60601-1-2 (Electromagnetic compatibility), and are certified according
to IEC Standard 60950 (Information Technology Equipment (ITE)).

WARNING: SonoSite does not currently recommend a specific brand of acoustic standoff. If an
acoustic standoff is used, it must have a minimum attentuation of .3dB/cm/MHz.
Some SonoSite transducers are approved for intraoperative applications if a
market-cleared sheath is used.
Caution: Medical electrical equipment requires special precautions regarding EMC and must
be installed and operated according to these instructions. It is possible that high
levels of radiated or conducted radio-frequency electromagnetic interference (EMI)
from portable and mobile RF communications equipment or other strong or nearby
radio-frequency sources, could result in performance disruption of the ultrasound
system. Evidence of disruption may include image degradation or distortion, erratic
readings, equipment ceasing to operate, or other incorrect functioning. If this occurs,
survey the site to determine the source of disruption, and take the following actions
to eliminate the source(s).
•Turn equipment in the vicinity off and on to isolate disruptive equipment.
•Relocate or re-orient interfering equipment.
•Increase distance between interfering equipment and your ultrasound system.
•Manage use of frequencies close to ultrasound system frequencies.
•Remove devices that are highly susceptible to EMI.
•Lower power from internal sources within facility control (such as paging
systems).
•Label devices susceptible to EMI.
•Educate clinical staff to recognize potential EMI-related problems.
•Eliminate or reduce EMI with technical solutions (such as shielding).
•Restrict use of personal communicators (cell phones, computers) in areas with
devices susceptible to EMI.
•Share relevant EMI information with others, particularly when evaluating new
equipment purchases which may generate EMI.
•Purchase medical devices that comply with IEC 60601-1-2 EMC Standards.

Electrostatic discharge (ESD), or static shock, is a naturally occurring phenomenon.
ESD is common in conditions of low humidity, which can be caused by heating or air
conditioning. Static shock is a discharge of the electrical energy from a charged
body to a lesser or non-charged body. The degree of discharge can be significant
enough to cause damage to a transducer or an ultrasound system. The following
precautions can help reduce ESD: anti-static spray on carpets, anti-static spray on
linoleum, and anti-static mats.

Field strengths from fixed RF
transmitters, as determined by
an electromagnetic Site
surveya, should be less than
the compliance level in each
frequency rangeb.
Interference may occur in the
vicinity of equipment marked
with the following symbol:
(IEC 60417 No. 417-IEC-5140:
“Source of non-ionizing
radiation”)
Note: UT is the AC mains voltage prior to application of the test level.
At 80 MHz and 800 MHz, the higher frequency range applies.
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
a.Field strengths from fixed transmitters such as base stations for radio (cellular/cordless) telephones and
land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which
the SonoSite ultrasound system is used exceeds the applicable RF compliance level above, the SonoSite
ultrasound system should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the SonoSite ultrasound system.
b.Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

as low as reasonably
achievable (ALARA)
The guiding principle of ultrasound use, which states that you should
keep patient exposure to ultrasound energy as low as reasonably
achievable for diagnostic results.
curved array
transducer
Identified by the letter C (curved or curvilinear) and a number (60). The
number corresponds to the radius of curvature of the array expressed
in millimeters. The transducer elements are electrically configured to
control the characteristics and direction of the acoustic beam. For
example, C15, C60e.
depth Refers to the depth of the display. A constant speed of sound of
1538.5 meters/second is assumed in the calculation of echo position in
the image.
in situ In the natural or original position.
LCD liquid crystal display
linear array
transducer
Identified by the letter L (linear) and a number (38). The number
corresponds to the radius of width of the array expressed in
millimeters. The transducer elements are electrically configured to
control the characteristics and direction of the acoustic beam. For
example, L38.
mechanical index
(MI)
An indication of the likelihood of mechanical bioeffects occurring: the
higher the MI, the greater the likelihood of mechanical bioeffects. See
Chapter 6, “Safety,” for a more complete description of MI.
MI/TI See mechanical index (MI) and thermal index (TI).
NTSC National Television Standards Committee. A video format setting. See
also PAL.
PAL Phase Alternating Line. A video format setting. See also NTSC.
phased array A transducer designed primarily for cardiac scanning. Forms a sector
image by electronically steering the beam direction and focus.
90
skinline A depth on the display that corresponds to the skin/transducer
interface.
SonoHD™ imaging
technology
A subset of the 2D imaging mode in which the 2D image is enhanced
by reducing speckle noise artifact at tissue margins and improving
contrast resolution by reducing artifacts and improving visualization of
texture patterns within the image.
SonoMB technology A subset of the 2D imaging mode in which the 2D image is enhanced
by looking at a target from three angles and then merging or averaging
the scanned data together to improve overall image quality and, in
parallel, reducing noise and artifacts.
thermal index (TI) The ratio of total acoustic power to the acoustic power required to raise
tissue temperature by 1°C under defined assumptions. See Chapter 6,
“Safety,” for a more complete description of TI.
TIB (bone thermal
index)
A thermal index for applications in which the ultrasound beam passes
through soft tissue and a focal region is in the immediate vicinity of
bone.
TIC (cranial bone
thermal index)
A thermal index for applications in which the ultrasound beam passes
through bone near the beam entrance into the body.
TIS (soft tissue
thermal index)
A thermal index related to soft tissues.
Tissue Harmonic
Imaging
Transmits at one frequency and receives at a higher harmonic
frequency to reduce noise and clutter and improve resolution.
transducer A device that transforms one form of energy into another form of
energy. Ultrasound transducers contain piezoelectric elements, which
when excited electrically, emit acoustic energy. When the acoustic
energy is transmitted into the body, it travels until it encounters an
interface, or change in tissue properties. At the interface, an echo is
formed that returns to the transducer, where this acoustic energy is
transformed into electrical energy, processed, and displayed as
anatomical information.
