What Is a Doppler Fetal Monitor?
Doppler fetal monitors provide continuous monitoring, display, and recording of fetal heart rate (FHR), as well as prenatal uterine function (UA) testing and monitoring.

- Doppler fetal monitors provide continuous monitoring, display, and recording of fetal heart rate (FHR), as well as prenatal uterine function (UA) testing and monitoring. This device may only be used by trained healthcare personnel in hospitals, clinics, clinics, and patients' homes.
- Doppler fetal instruments are mainly used to provide continuous monitoring, display and recording of fetal heart rate (FHR), as well as prenatal uterine function (UA) testing and monitoring. Fetal monitoring is provided by general maternity hospitals.
- The Doppler fetal monitor is a non-invasive prenatal monitoring system that displays the mother's abdominal contractions and fetal heart rate through waveforms and charts, and can record data on a strip chart recorder. This data can assist in the assessment of the health status of the fetus before delivery (stress response test). Use of this device is restricted to trained medical personnel in hospitals, clinics, clinics, and patient homes.
- Monitoring data can be continuously or intermittently recorded on the strip chart recorder as required by the operator. The recorded information includes chart trend data and monitor software and hardware status information, time and date, patient number, operation setting changes, and patient and clinician event markers.
- Doppler effect: The wavelength of radiation changes due to the relative movement of the light source and the observer. In front of a moving wave source, the wave is compressed, the wavelength becomes shorter, and the frequency becomes higher (blue shift). Behind the wave source of motion, the opposite effect occurs. The wavelength becomes longer and the frequency becomes lower (red shift). The higher the velocity of the wave source, the greater the effect. According to the red / blue shift of the light wave, the speed of the wave source moving in the observation direction can be calculated. The displacement of a star's spectral line shows how fast the star is moving in the direction of observation. Unless the speed of the wave source is very close to the speed of light, the degree of Doppler shift is generally small. All wave phenomena (including light waves) have a Doppler effect.
