SonicaidOne User Guide

Description

The SonicaidOne operates at a nominal frequency of 2MHz, using Doppler ultra-
sound to detect the fetal heart. The fetal heart may be detected from early
pregnancy, but more easily in pregnancies later than 15 weeks gestation. It is
light, fits comfortably into a pocket, and is suitable for
use in the antenatal or labour period. A headset is an optional extra.
The SonicaidOne has a waterproof probe and cable. The main unit is not
waterproof. The SonicaidOne is suitable for labour use, and for use in the
clinical management of water births, provided the main unit is kept dry.

Examination

Caution:
1 Use the SonicaidOne only on intact skin.
2 Take care at all times not to drop the unit.
3 Always inspect the unit for damage prior to use.
Notes:
Always use ultrasound gel between the transducer face and the mother's
abdomen.
To ensure that the signal detected is fetal in origin, always take the maternal
pulse prior to attempting fetal heart detection.
During very early pregnancy, it is often difficult to obtain the fetal heartbeat. If
you do have difficulty finding a signal, please try not to alarm the patient.
Reassure her that this is quite normal.
1 Apply a small amount of ultrasound gel to the probe face.
2 Switch on by holding down the green button for 2 or 3 seconds.
3 In early pregnancy:
place the probe face on the medial line just above the symphysis pubis with
moderate pressure; tilt slowly in various directions until the heart beats are
heard. If no beats are detected, move the transducer a few centimetres
higher and repeat the procedure. Note that the patient should be advised, if
possible, to have a full bladder as this would facilitate the transmission of
ultrasound.
