Patient Safety
This section describes issues and situations that can affect patient safety when you
are using the ultrasound system.
Ultrasound Exposure
Although no harmful effects have been demonstrated for the ultrasound frequen-
cies, intensities, and exposure times used in examinations with Philips ultrasound
systems, Philips recommends that you select the lowest ultrasound exposure that
produces diagnostically acceptable information.
Follow these guidelines to reduce ultrasound exposure:
• Use diagnostic ultrasound only when there is a good medical reason.
• Reset controls at the start of every examination.
• Reduce exposure time, independent of the acoustic index value.
• Use techniques that enable you to both collect clinical data and end the exam-
ination quickly.
•Use a transducer that provides the best possible resolution and penetration.
For more detailed information on ultrasound exposure, see the Output Display
Standards and ODS Acoustic Tables booklet.
The following symbols appear on the product packaging to indicate environmental
considerations:
Atmospheric
pressure
Atmospheric pressure range of 572 to 1,013 hPa for
transport and storage.
Relative
humidity
Relative humidity range of 20% to 90% (noncondensing) for
transport and storage.
Ambient
temperature
Ambient temperature range –20
°
C to +60°C (–4°F to
+140°F) (noncondensing) for transport and storage. (Does
not apply to media.)
