Fetal monitor Mediana FM-20 records data on three indicators: uterine contraction (UC), fetal heart rate (FHR) and fetal movement (FM). It can be used throughout the entire period of pregnancy, for examination in a medical institution and in an ambulance. Fetal heart sounds can be recorded in real time by connecting a personal computer running Mediana software. The device works correctly in the FHR range from 30 to 240 beats per minute. Dual pulsed Doppler technology is used, providing an accuracy of 2%.
