What is Doppler's probe?
Doppler probe is the device most commonly used in medical applications to measure the shift in sound waves emitted and reflected back to the device. The probe allows measuring and visualization or simulating the sound of the movement of substances in the body. Doppler probes are most commonly used in cardiovascular applications and to confirm and monitor pregnancy in humans and animals.
Generally, the Doppler probe uses the Doppler effect principle to assess whether something is moving and the relative speed of movement. Doppler effect is a change in the frequency of wool - usually sound wool, but also applicable to other types of radiation waves - because the source moves to the observer. Each wave frequency seems higher when the object is close to the observer and lower when it moves. Information about the Doppler probe can be used to assess how quickly something moves and its direction of travel.
Doppler probes are most commonly used in the medical environment. Their use is the monitoring of the heart of the fetus, localization of blood vessels before surgery to prevent their unintentionally interruption and monitoring of the speed and direction of blood flow during cardiovascular surgery. The probes are also used in the diagnosis of portal hypertension, liver disease, where blood flow is reversed with veins and liver arteries.
Heart heart monitoring is available for doppler probes for clinical and home use. Expectant parents use them to experience the sound of the heart that beats the heart before birth. 3MH probes are used to detect heart rate in early pregnancy, usually in 8-10 weeks of pregnancy, while 2Mh Sondas are used for pregnant women with overweight. Some Doppler probes monitoring fetus are waterproof, so they can be used during underwater births. A popular myth on the monitoring of the heart rate of the doppler probe of the tightthe fact that the results can be used to predict the sex of the child; However, this idea is not supported by scientific evidence.
Doppler probes of different sizes and connections are often used during surgery. The probe is used to verify that blood reaches the body. It is also used to find blood vessels to maintain them during surgery.
