ALARA
Training
It is recommended that all users receive proper training in
applications before performing them in a clinical setting. Please
contact the local GE representative for training assistance.
ALARA training is provided in the Medical Ultrasound Safety
booklet shipped in the eDOCs kit. The ALARA education
program for the clinical end-user covers basic ultrasound
principles, possible biological effects, the derivation and
meaning of the indices, ALARA principles, and examples of
specific applications of the ALARA principle.
This equipment provides no special means of protection from
high frequency (HF) burns that may result from using an
electrosurgical unit (ESU). To reduce the risk of HF burns,
avoid contact between the patient and ultrasound transducer
while operating the ESU. Where contact cannot be avoided, as
in the case of TEE monitoring during surgery, make sure the
transducer is not located between the ESU active and
dispersive electrodes and keep the ESU cables away from the
transducer cable.
Ultrasound can produce harmful effects in tissue and
potentially result in patient injury. Always minimize exposure
time and keep ultrasound levels low when there is no medical
benefit. Use the principle of ALARA (A
s Low As Reasonably
A
chievable), increasing output only when needed to obtain
diagnostic image quality. Observe the acoustic output display
and be familiar with all controls affecting the output level. See
the Bioeffects section of the Acoustic Output chapter in the
Advanced Reference Manual for more information.
