Tips :
1. When measuring, pregnant mothers should lie flat or semi-reclining, maintain a good mood, measure in a quieter environment, move as little as possible, and stay away from electrical interference.
2. After hearing the baby's stable and continuous fetal heart sound, stand still for 3-5 seconds, so that the fetal heart rate probe receives a stable and continuous fetal heart signal, and the value displayed at this time is the accurate fetal heart rate. Note that the value at this time is not static, but will fluctuate slightly. In the process of finding the fetal heart, the movement should be slow, the amplitude should not be too large, and press a little harder.
