WARNING: To prevent misdiagnosis or harm to
the patient, understand your
systems capabilities prior to use.
The diagnostic capability differs for
each transducer, exam type, and
imaging mode. In addition,
transducers have been developed
to specific criteria depending on
their physical application. These
criteria include biocompatibility
requirements.
To avoid injury to the patient, use
only an Orbital (Orb) or Ophthalmic
(Oph) when performing imaging
through the eye. The FDA has
established lower acoustic energy
limits for ophthalmic use. The
system will not exceed these limits
only if the Orb or Oph exam type is
selected.

Measurements
a. The Gestational Age is automatically calculated and displayed
next to the OB measurement you selected. The average of the
results is the AUA.
b. For Tokyo U., APTD and TTD are used only to calculate EFW. No
age or growth tables are associated with these
measurements.
c. The Estimated Fetal Weight calculation uses an equation that
consists of one or more fetal biometry measurements. The
author for the OB tables, which you choose on a system setup
page, determines the measurements you must perform to
obtain an EFW calculation. (See “OB Calculations setup” on
page 20.)
Individual selections for Hadlocks EFW equations 1, 2, and 3
are not determined by the user. The selected equation is
determined by the measurements that have been saved to
the patient report with priority given to the order listed
above.
d. The Growth Analysis tables are used by the Report Graphs
feature. Three growth curves are drawn using the table data
for the selected growth parameter and published author.
Growth tables are only available with a user-entered LMP or

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 contacts during use. To
avoid infection, ensure that the
disinfectant type and the solution
strength and duration are
appropriate for the equipment. For
information, see the disinfectant
label instructions and the
recommendations of the
Association for Professionals in
Infection Control and Epidemiology

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.
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 system
from the power supply or remove
from the mini-dock or docking
system.
To avoid infection always use
protective eyewear and gloves
when performing cleaning and
disinfecting procedures.
To avoid infection, ensure that the
solution expiration date has not
passed.
Caution: Do not spray cleaners or
disinfectant directly on the system
surfaces. Doing so may cause
solution to leak into the system,
damaging the system and voiding
the warranty.
Do not use strong solvents such as
thinner or benzene, or abrasive
cleansers, since these will damage
the exterior surfaces.
Use only recommended cleaners or
disinfectants on system surfaces.
Immersion-type disinfectants are
not approved for use on system
surfaces.
When you clean the system, ensure
that the solution does not get
inside the system controls or the
battery compartment.
Do not scratch the LCD screen.

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.
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 disorders (MSDs)a,b,c.
Use of an ultrasound system is defined as the physical interaction between 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 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.

Formaximumsafetyobservethefollowingwarningsandcautions.
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 a
docking system 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.
Chapter 6: Safety 89
Safety
WARNING: 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 to the patient, do not simultaneously touch the
patient and the ungrounded signal input/output connectors on the back of the
ultrasound system.
To avoid the risk of electrical shock and fire hazard, inspect the power supply, AC
power cords, cables, and plugs on a regular basis. Ensure that 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 MDS to mains power must only be
used with the power supply or docking system, and cannot be used to connect
other devices to mains power.
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, use commercial grade peripherals
recommended by SonoSite on battery power only. Do not connect these products
to AC mains power when using the system to scan or diagnose a patient/subject.
Contact SonoSite or your local representative for a list of the commercial grade
peripherals available from or recommended by SonoSite.
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)).
Caution: Do not use the system if an error message appears on the image display: note the
error code; call SonoSite or your local representative; turn off the system by pressing
and holding the power key until the system powers down.
To avoid increasing the system and transducer connector temperature, do not block
the airflow to the ventilation holes on the side of the system.

battery with the system.
92
Clinical safety
WARNING: Non-medical (commercial) grade peripheral monitors have not been verified or
validated by SonoSite as being suitable for diagnosis.
To avoid the risk of a burn hazard, do not use the transducer with high frequency
surgical equipment. Such a hazard may occur in the event of a defect in the high
frequency surgical neutral electrode connection.
Do not use the system if it exhibits erratic or inconsistent behavior. Discontinuities in
the scanning sequence are indicative of a hardware failure that must be corrected
before use.
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.
Perform ultrasound procedures prudently. Use the ALARA (as low as reasonably
achievable) principle and follow the prudent use information concerning MI and TI.
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.
To avoid injury or reduce the risk of infection to the patient, observe the following:
• Follow Universal Precautions when inserting and maintaining a medical device
for interventional and intraoperative procedures.
Appropriate training in interventional and intraoperative procedures as dictated
by current relevant medical practices as well as in proper operation of the
ultrasound system and transducer is required. During vascular access, the
potential exists for serious complications including without limitation the
following: pneumothorax, arterial puncture, guidewire misplacement, and risks
normally associated with local or general anesthesia, surgery, and post-operative
recovery.
To avoid device damage or patient injury, do not use the P10x, P17x, or P21x needle
guide bracket on patients with pacemakers or medical electronic implants. The
needle guide bracket for the P10x, P17x, and P21x transducers contains a magnet
that is used to ensure the bracket is correctly oriented on the transducer. The
magnetic field in direct proximity to the pacemaker or medical electronic implant
may have an adverse effect.

Caution: To avoid the risk of increased electromagnetic emissions or decreased immunity, use
only accessories and peripherals recommended by SonoSite. Connection of
accessories and peripherals not recommended by SonoSite could result in
malfunctioning of your ultrasound system or other medical electrical devices in the
area. Contact SonoSite or your local representative for a list of accessories and
peripherals available from or recommended by SonoSite. See the SonoSite
accessories user guide.
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.

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.

WARNING: The gestational age calculated by
your SonoSite system does not
match the age in the
aforementioned reference at the
20.0 cm and 30.0 cm abdominal
circumference (AC) measurements.
The implemented algorithm
extrapolates the gestational age
from the slope of the curve of all
table measurements, rather than
decreasing the gestational age for a
larger AC measurement indicated in
the referenced table. This results in
the gestational age always
increasing with an increase in AC.

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.
158
skinline A depth on the display that corresponds to the skin/transducer
interface.
SonoHD 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 A subset of the 2D imaging mode in which the 2D image is enhanced
by looking at a target from multiple angles and then merging or
averaging the scanned data together to improve overall image quality
and, in parallel, reducing noise and artifacts.
Tissue Doppler
Imaging (TDI)
A pulsed wave Doppler technique used to detect myocardial motion.
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.
variance Displays a variation in Color Doppler flow imaging within a given
sample. Variance is mapped to the color green and is used to detect
turbulence.
