– BPL First Beats is a Foetal Heart Detector that provides an audible simulation of the foetal heartbeat in an accurate & sensitive manner
– This fetal heart monitor is portable and is light in weight
– Its unique technology helps to acquire clear foetal heartbeat by minimizing ultrasound noise
– A high sensitivity probe enables the detection of beats of a foetus more than 16 weeks old
– The fetal heart rate monitor has a single button operation making it easy to use
– The fetal heartbeat monitor provides synchronous audio output signals, accessible for headphones or recording devices. Headphones & recording devices can be connected to this device easily

- Foetal Heart Monitor or foetal Doppler is handheld ultrasound monitor used to hear an embryo’s heartbeat.
- The Foetal Doppler machine emits ultrasound waves into the area and the foetal heart reflects these waves emitted by the Doppler foetal heart monitor.
- The foetal heart monitor detects frequency change and then transforms it into sounds. Foetal Doppler provides an audible stimulation of heart beat and may also display heart rate in Beats per minute.
- The foetal Doppler is used by exposing the abdomen and applying ultrasound or fetal doppler gel and placing the probe in the fetal doppler gel before turning on the foetal doppler mahine.
- The probe of the foetal doppler is glided from the pubic bone towards the umbilicus till foetal heartbeat is detected by the foetal doppler.
- Fetal Doppler scan at 6 weeks usually detects embryonic heartbeat. Foetal Doppler at 9 weeks usually detects 160-180 beats per minute. Fetal Doppler ultrasound normal values should be discussed with your doctor.
- Doppler Ultrasound for fetal heartbeat is usually very accurate, but still, the Doppler ultrasound fetal heart rate should be discussed with a doctor when in doubt.
