OB Exam
Exam Preparation
Prior to an ultrasound examination, the patient should be 
informed of the clinical indication, specific benefits, potential 
risks, and alternatives, if any. In addition, if the patient requests 
information about the exposure time and intensity, it should be 
provided. Patient access to educational materials regarding 
ultrasound is strongly encouraged to supplement the information 
communicated directly to the patient. Furthermore, these 
examinations should be conducted in a manner and take place 
in a setting which assures patient dignity and privacy.
•  Prior material knowledge and approval of the presence of 
nonessential personnel with the number of such personnel 
kept to a minimum.
•  An intent to share with the parents per the physician’s 
judgement, either during the examination or shortly 
thereafter, the information derived. 
•  An offer of choice about viewing the fetus.
•  An offer of choice about learning the sex of the fetus, if such 
information becomes available.
Ultrasound examinations performed solely to satisfy the familys 
desire to know the fetal sex, to view the fetus, or to obtain a 
picture of the fetus should be discouraged.

Acoustic Output Considerations
General warning
The LOGIQ 5 system is a multi-use device which is capable of 
exceeding FDA Pre-enactment acoustic output (spatial peak-
temporal average) intensity limits for fetal applications.
Concerns surrounding fetal exposure
Always be aware of the acoustic output level by observing the 
Acoustic Output Display. In addition, become thoroughly familiar 
with the Acoustic Output Display and equipment controls 
affecting output.
Training
It is recommended that all users receive proper training in fetal 
Doppler applications before performing them in a clinical setting. 
Please contact a local sales representative for training 
assistance.
CAUTIONIt is prudent to conduct an exam with the minimum amount and 
duration of acoustic output necessary to optimize the images 
diagnostic value.
