GENERAL HINTS
Use plenty of coupling gel.
Ultrasound is almost completely stopped by any air or
bubbles between the skin and the probe. Use the ultrasound gel liberally for best results.
Move the probe slowly.
When searching for the fetal heart, a slow rocking and rotating
motion will minimize noise and help avoid missing the heartbeat. Rest your hand on the
patient to stabilize the probe and to avoid unwanted motion and noise.
Maintain probe contact.
It is important to keep the entire probe face in contact with the
skin surface. Holding the probe in this manner allows you to obtain the best possible
sounds.
Angling.
The 2 MHz, 3 MHz and 5 MHz probes are designed to achieve optimum
results without angling - lay the probe face down against the skin. The 8 MHz probe
requires an approximate 45° angle for optimum results.
Carrying the unit.
Always check the probe to make sure it is completely seated in the
holding clips. Never presume the probe is lodged tightly.
