The goal is often to check blood flow through the arms and legs.ĭuring a Doppler ultrasound, a handheld device emits sound waves that bounce off moving objects, such as blood cells. For questions regarding medical conditions, please consult with a medical health professional.Share on Pinterest A doctor can use a Doppler ultrasound to check blood flow.Ī Doppler ultrasound uses sound waves to create images of how a person’s blood is flowing through their veins and arteries. The use of the machine provides audio and heart rate value that is for non-medical purposes only. All activity that is monitored and viewed with the device should not be considered a medical conclusion. It is not an approved device for the treatment or prevention of medical conditions. This product is not a diagnostic instrument. A 3.0MHz probe has also been proven to work well throughout the pregnancy. It works better because the fetus is so small early in gestation that 3.0MHz probe reflects the ultrasound back to the sensor better than the lower frequency 2.0MHz probe. Over 90% of OBs, hospitals, and midwives choose 3 MHz probe because they know from the results of millions of exams that 3 MHz probe works better. Why do we recommend 3 MHz probes for fetal heart detection? This mode allows the user to calculate an average heart rate over a specific period of time by manually pushing a button to start & stop the time.
