What is Doppler's test?

Doppler test is a non -invasive medical test used to investigate blood flow through the main arteries. Sometimes it is called Doppler's ultrasound, the test helps doctors to identify blockages before it can lead to health complications such as stroke. Doppler imaging also helps doctors to diagnose conditions such as arterial occlusion, blood clots, tumors and problematic problems with arteries and veins.

For the test, a converter that is a manual device is used to perform the test. The converter is covered with soluble water, doppler gel, placed over the skin, above the blood vessel. It makes high -frequency sound waves that are reflected from the tested veins or arteries. If the blood flow rate changes, the sound frequency changes noticeably. Like the method of radar weapon, the driving speed measures, the Doppler test measures the speed and efficiency of blood flow. If blood flow is smooth and continuous, the test is normal. If blockade is present, the results of the Doppler test will return the abnormal repetitionT.

abnormal results can indicate different problems. Some potential problems include arterial blocking, closed veins or tumors. The doctor is required to interpret the results of doppler tests.

Doppler test is also used during pregnancy to monitor blood flow. The right flow from the mother to the child is crucial for the child's health. The test also allows doctors to monitor and assess the child's heart rhythm. In fact, the machine can be rented by the expectations of their parents, allowing them to perform a Doppler test at home and listen to their child at any time.

Sometimes a doppler ultrasound is performed Color . This version of the test converts the sound wave to color results. Color tests are sometimes used to identify cancer tumors that are identified because they generally show an increase in blood flow. While doctors are qualified when reading both types of tests, the color versionIt is usually easier to read.

Doppler tests require almost no preparation from the patient. The patient must simply remove all clothes from the area to be tested. Because nicotine can affect the results of doppler tests - because it causes the veins to be reduced - patients may be obliged to delay smoking for a period of time before testing. As a non -invasive test, the Doppler test causes a small or no discomfort and there is no small or no risk to the procedure.
