Moreover, Doppler auscultation was superior in the detection of impaired ventricular relaxation Since the physics of Doppler auscultation and classic auscultation are different, it has been suggested that both methods could complement each other. The Doppler auscultation presented a sensitivity of 84% for the detection of aortic regurgitations, while classic stethoscope auscultation presented a sensitivity of 58%. It was recently demonstrated that continuous Doppler enables the auscultation of valvular movements and blood flow sounds that are undetected during cardiac examination with a stethoscope in adults. One disadvantage is the greater complexity and cost and the lower reliability of an electronic device. One advantage of the Doppler fetal monitor over a (purely acoustic) fetal stethoscope is the electronic audio output, which allows people other than the user to hear the heartbeat. It may be classified as a form of Doppler ultrasonography (although usually not technically -graphy but rather sound-generating).ĭoppler fetal monitors provide information about the fetus similar to that provided by a fetal stethoscope. The Doppler fetal monitor is commonly referred to simply as a Doppler or fetal Doppler. Use of this monitor is sometimes known as Doppler auscultation. Some models also display the heart rate in beats per minute (BPM). It uses the Doppler effect to provide an audible simulation of the heart beat.

Contact us online to learn more about Doppler ultrasounds and request an appointment today. Consult with one of our cardiologists to determine if this test is right for you. They might suggest an ultrasound if you're at risk of stroke or show signs of poor circulation.Īt Modern Health and Vascular, our experts understand the importance and benefits of cardiovascular imaging for your health. Reach Out to a Cardiologist Todayĭoctors use the data from Doppler ultrasounds to identify underlying conditions, determine the proper treatments and reduce your risk of stroke and other issues. The sound waves bounce off the vein and the transducer records the returning echo, turning it into a visual graphic. The transducer emits sound waves that help create images of your blood vessels. Depending on the artery under examination, the sonographer runs the transducer over your legs, arms, neck (for carotid Doppler ultrasounds) or other body parts. This diagnostic exam is painless, often lasts under an hour and has no side effects.ĭuring a Doppler ultrasound, a technician (known as a sonographer) uses a wand-like tool called a transducer. How Does a Doppler Ultrasound Work?Ī Doppler ultrasound is a no-pain, no-risk alternative to more invasive tests. Your doctor can use these images and relevant data to make a diagnosis or establish a treatment plan. If there is a clot, plaque buildup or another issue, it will appear on the ultrasound. These noninvasive exams use sound waves to create images of your veins, enabling doctors to examine blood flow and pressure throughout your body. The purpose of a Doppler ultrasound is to give your doctor a better look at the condition of your veins, allowing your physician to identify the cause of your circulatory problems. Limited blood flow or blockages can lead to strokes, deep vein thrombosis (DVT) and other life-threatening conditions. When narrowed or blocked blood vessels interrupt this system, they can cause serious problems. Good circulation is necessary to stay healthy. Blood vessels are the veins and arteries that carry blood from your heart to your other organs and limbs. Your cardiovascular system circulates blood throughout your entire body. Modern Health and Vascular uses advanced technology to provide patient-focused cardiovascular care such as this test and many more options. A Doppler ultrasound is a standard diagnostic test that allows your doctor to check blood circulation in the blood vessels throughout your body. Electronic fetal monitoring is a procedure in which instruments are used to continuously record the heartbeat of the fetus and the contractions of the womans.
