The Doppler fetal monitor is commonly referred to simply as a Doppler or fetal Doppler. It may be classified as a form of Doppler ultrasonography (although usually not technically -graphy but rather sound-generating). Doppler fetal monitors provide information about the fetus similar to that provided by a fetal stethoscope. One advantage of the ...
Fetoscopy is a surgical procedure which may involve the use of a fibreoptic device called a fetoscope. Some confusion may arise from the use of specialized forms of stethoscopes, including Pinard horns and Doppler wands, to audibly monitor fetal heart rate (FHR). These audio diagnostic tools are also called "fetoscopes" but are not related to ...
Doppler ultrasonography is medical ultrasonography that employs the Doppler effect to perform imaging of the movement of tissues and body fluids (usually blood), [1] [2] and their relative velocity to the probe. By calculating the frequency shift of a particular sample volume, for example, flow in an artery or a jet of blood flow over a heart ...
Fetoscope may refer to: the kind of endoscope used in fetoscopy; fibreoptic scope for looking directly at the fetus, as opposed to a stethoscope used to listen the heart beat; the Pinard horn fetal stethoscope; Doppler ultrasound or Medical ultrasonography "wands"
The Doppler effect (also Doppler shift) is the change in the frequency of a wave in relation to an observer who is moving relative to the source of the wave. [ 1 ] [ 2 ] [ 3 ] The Doppler effect is named after the physicist Christian Doppler , who described the phenomenon in 1842.
Another alternative is the fetoscope, which is a stethoscope designed for auscultating fetuses. Below is a quote from a midwife in Mexico describing the Pinard horn: Sometimes we listen to the fetal heart rate with the Pinard, but if the woman is very sensitive, and it bothers her to push into her belly with the Pinard horn, then we use the ...

A Doppler stethoscope is an electronic device that measures the Doppler effect of ultrasound waves reflected from organs within the body. Motion is detected by the change in frequency, due to the Doppler effect, of the reflected waves. Hence the Doppler stethoscope is particularly suited to deal with moving objects such as a beating heart. [28]
