Dopplers

A Doppler simply uses sound waves to produce images of the blood moving through the human circulatory system. It can help to diagnose many conditions that include blood clots, poorly functioning valves in your body veins, heart valve defects and also congenital heart disease.

Depending on what the Doppler is to be used for you must ensure equipment is in good working condition and make sure the patient lies down flats. 

Then you can place the sphygmomanometer cuff around your arm and put a gel over the brachial pulse. You can then proceed to hold the Doppler probe gently over the brachial pulse until you get a good signal and then take the readings. Repeat the process to be sure of your results.

The main reason why dopplers are used is to help medical personnel find out if you have a condition that is restricting or reducing your blood flow. It can detect diseases like peripheral arterial disease (PAD), diabetic foot ulcer and other heart conditions.

An ultrasound is used to view and provide information about the internal parts of the body such as the heart, kidneys, blood vessels, liver, bladder and even reproductive organs. The test is also used to provide information about fetus growth, development, and overall health.

According to the https://www.fda.gov/consumers/consumer-updates/avoid-fetal-keepsake-images-heartbeat-monitors

, and the Food and Drug Administration, using fetal dopplers is only preferred when a doctor is using them and is medically necessary.

The difference between the Doppler ultrasound sound and the regular one is that the Doppler test is noninvasive and it’s used to estimate the blood flow in the blood vessels and ensure circulation of red blood cells. A normal ultrasound only use sound waves to produce images, without showing blood flow.
