![]() ![]() Post-exposure scheme, people not vaccinated against rabies, consists of five doses of rabies vaccine. Third dose 28 days after the first dose.Ģ.Second dose 7 days after the first dose.Pre-exposure scheme, consists of three doses of rabies vaccine: It is recommended for certain international travelers, based on the occurrence of animal rabies in the destination country.ġ. Prevention of rabies in subjects exposed to risk of contamination.Vaccination is indicated in the following cases: It is characterized by acute encephalomyelitis (an aggressive response of the immune system that destroys the myelin layer of the nerves and alters its function at the level of the brain or spinal cord). Human rabies is a viral disease transmitted by the bite of an infected animal. Contact us! Cardiovascular Diagnostic Center If you want to know more about the echo-doppler procedure, come to the ABC Medical Center’s Cardiovascular Diagnostic Center, we can provide you with specialized attention. This content is for informational purposes and does not replace any consultation with the specialist. Obstruction or occlusion in the neck, arms, and leg arteries.Evaluation of the renal and intra-abdominal arteries.It is a non-invasive and painless procedure, and since it does not require ionizing radiation (X-rays), it can be used in a wide variety of patients. What is the cardiac echo-doppler used for? The spectral Doppler displays the measurement results in a separate graph, indicating the recorded blood flow velocities. Power Doppler is a useful technique to demonstrate if there is blood flow in an area, although it does not indicate the direction of the existing flow. Allowing the evaluation of the main arteries and veins, the heart, and fetal monitoring in obstetrics.ĭepending on the equipment used, echo-doppler can be continuous or pulsed the latter can be divided into three types:Ĭardiac color Doppler is a type of ultrasound that uses a computer to convert sound waves into different colors, showing blood’s speed and direction in real time. How is a cardiac echo-doppler performed?īeing a study similar to a conventional ultrasound, it differs by using the “Doppler effect”, focusing on the change in the frequency of the sound received concerning the sound emitted. For an echo-Doppler, an ultrasound imaging technician, known as a sonographer, presses a small handheld transducer onto the skin of the area of the body to be examined. This test is an alternative to more invasive procedures, such as an arteriogram where a dye must be injected. With the echo-doppler, it is possible to calculate the blood flow speed by measuring its frequency changes. This study uses sound waves that show blood circulation through the vessels, also allowing the creation of images of internal structures of the body through said waves, which results in the visualization of blood circulation. The echo-doppler, also known as Doppler ultrasound, is a non-invasive test used to calculate the flow of blood in blood vessels. ![]()
