Healthy Scanning Guidelines
These guidelines are intended to assist you in the comfortable and effective use of your hand carried
ultrasound system.
Warning: Use of an ultrasound system may be linked to musculoskeletal disordersa,b,c.
Use of an ultrasound system is defined as the physical interaction between the
operator, the ultrasound system, and 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.

8Chapter 2: Getting Started
Getting Started
Position the System
To promote comfortable shoulder, arm and hand postures, consider the following:
•Use a stand to support the weight of the ultrasound system.
•If a stand is not available, use the patient bed, other furniture in the patient room, or your
leg/knee to support the weight of the ultrasound system. Do not operate the ultrasound system
without support, except for short term use.
Figure 1 Healthy Scanning Positions
•Use the ultrasound system handle pad appropriate for your hand size. Two handle pad sizes
are provided which allow for the handle opening size to be customized.
To minimize eye strain, consider the following:
•When the exam/procedure allows, position the system within reach.
•Adjust the angle of the system/display to minimize glare from overhead or outside lighting.
To minimize neck strain, consider the following:
•If using a stand, adjust the stand height such that the display is at or slightly below eye level.
Warning: Under prolonged use, the back of the 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. The ultrasound
system is labeled: SHORT TERM USE. (Short term use is based on a use model of
4-10 exams per day at 5 minutes per exam.)
Power off the system when not in use.

Chapter 2: Getting Started 9
Getting Started
Position Yourself
To support your back, consider the following:
•Use a chair that has support for your lower back.
•Use a chair that adjusts to your work surface height and promotes a natural body posture.
•Use a chair that allows for quick height adjustments.
•Always sit or stand in an upright manner. Avoid bending or stooping.
To minimize reaching and twisting, consider the following:
•Use an adjustable bed to adjust the height of the patient.
•Position the patient as close to you as possible.
•Face forward. Avoid twisting your head or body.
•Move your entire body front to back and position your scanning arm next to or slightly in front
of you.
•Stand for difficult exams to minimize reaching.
To promote comfortable shoulder and arm postures for your scanning arm, consider
the following:
•Keep your elbow close to your side.
•Relax your shoulders in a level position.
•Support your arm using a support cushion or pillow, or rest it on the bed.
To minimize neck bending and twisting, consider the following:
•Position the ultrasound system/display directly in front of you.
•Provide an auxiliary monitor for patient viewing.
Go Lightly
To promote comfortable hand, wrist, and finger postures for your scanning arm,
consider the following:
•Hold the transducer lightly in your fingers.
•Minimize the pressure applied on the patient.
•Keep your wrist in a straight position.
Take Breaks
Minimizing scanning time and taking breaks can be very effective in allowing your body to recover
from physical activity, which can help you avoid any MSDs. Some ultrasound tasks may require
longer or more frequent breaks. One way of taking a break is to stop and relax. However, simply
changing tasks can help some muscle groups relax while others remain or become active.

10 Chapter 2: Getting Started
Getting Started
To vary your daily activities, consider the following:
•Plan your work so there are breaks in between ultrasound exams.
•When scanning, use both system input devices, the touch screen and the directional controller.
•Work efficiently when performing an ultrasound exam by using the software and hardware
features correctly. Learn more about these features in Chapter 3 of this guide.
•Keep moving. Avoid sustaining the same posture by varying your head, neck, body, arm, and
leg positions.
Exercise
Targeted exercises can strengthen muscle groups, which may help you avoid MSDs. Contact a
qualified health professional to determine stretches and exercises that are right for you.
