Why need a fetal heart monitor?
Fetal heart monitoring shows fetal conditions by detecting fetal heart rate. It is especially helpful during the health care of high-risk pregnancy and expectant mothers with diseases such as diabetes and high blood pressure. Also, if you are a mother-to-be often worry about your baby, in addition to regular fetal heart examine at the hospital, this device can reassure you and make you always keep in touch with your little one at home.
When can I hear my baby’s heartbeats?
Is my baby’s heart rate normal?
The normal ranges for FHR after 12-week pregnancy are 120 to 160 BPM (beat per minute). An abnormal FHR value could reflect low oxygen, compressed umbilical cord, or other pregnancy dangers. If your baby’s FHR is out of the normal threshold, please contact your physician.
Through experiences, obstetricians discovered that 3.0 MHz probe works better for finding the early fetal heartbeat. Over 90% of OBs, hospitals and midwives use 3.0 MHz probes. They find that 3.0 MHz probe works better because it reflects the ultrasound back to the sensor better than the lower frequency 2.0 MHz.
A 2.0 MHz probe does better only in a few special cases, such as on very overweight mothers when the fetus lies very deep.
