Biological Safety
This section contains information about biological safety and a discussion of the
prudent use of the system.
A list of precautions related to biological safety follows; observe these precautions
when using the system. For more information refer to Medical Ultrasound Safety
on your user information CD.
WARNINGS
• Do not use the system if an error message on the video display indicates
that a hazardous condition exists. Note the error code, turn off power to
the system, and call your customer service representative.
• Do not use a system that exhibits erratic or inconsistent image updating.
Discontinuities in the scanning sequence indicate a hardware failure that
must be corrected before use.
• Perform ultrasound procedures prudently. Use the ALARA (as low as
reasonably achievable) principle.
• Use only acoustic standoffs that have been approved by Philips Ultrasound.
For information on ordering approved accessories, see "Supplies and
Accessories" on page 23.
• Verify the alignment of the biopsy guide before use. See the "Biopsy Guides"
section.
• Verify the condition of the biopsy needle before use. Do not use a bent
biopsy needle.
• Transducer covers may contain natural rubber latex. Those covers may
cause allergic reactions in some individuals. See "FDA Medical Alert on
Latex" on page 45.
• In contrast studies using a high-MI acoustic field, capillary rupture, due to
microbubble expansion within a capillary in an acoustic field, can cause
extravasation. References: (1) Skyba, D.M., Price, R.J., Linka, A.Z., Skalak,
