  • Page 16 Monitoring Position the patient as required - typically in the semi-supine position and pass the elastic belts around the patient’s abdomen. Typically, the contractions transducer is positioned at the level of the fundus of the uterus, while the ultrasound transducer is positioned lower on the abdomen at the level of the fetal heart.
  • Page 17 Belt Attachment Attach one end of the belt to the transducer by engaging one of the holes in the belt over the button on the top of the transducer. Keeping the transducer in position, tension the other end of the belt and engage the belt over the button, ensuring sufficient tension to keep the transducer in firm contact with the abdomen.
  • Page 18 Contractions Transducer Attach the contractions transducer in the same way as the ultrasound transducer. Do NOT use gel. Position over the fundus for best performance. Tighten the belt to ensure good contact. Press the contractions ‘zero’ button. This removes the pre-load due to the belt tension and sets the contractions trace to the baseline on the print-out and ‘UA’...
