Operator Safety
This section describes issues and situations that can affect operator safety when
you are using an ultrasound system.
Repetitive Strain Injury
Repetitive ultrasound scanning has been associated with carpal tunnel syndrome
(CTS) and related musculoskeletal problems. Some investigators

have looked at a
large population of sonographers with different types of equipment. An article

,
with feedback from a smaller geographical area, makes the following recommen-
dations:
• Maintain your joints in optimum positions with a balanced posture while scan-
ning.
• Allow frequent breaks to give soft tissue a chance to recuperate from awk-
ward positions and repetitive movement.
• Avoid gripping the transducer with excessive force.
NOTE
The S3-1, S4-2, and S8-3 transducers are shipped with an ergonomic grip. To
order additional ergonomic grips, contact your Philips representative. To learn
how to install and clean the ergonomic grip, see “Installing and Cleaning the Ergo-
nomic Grip” on page 156.
