Pulsed Wave Doppler can be used as a New Method of Measuring Blood Pressure

Abstract

Hypertension is a chronic condition in which the force of blood pushing against the walls of your arteries is consistently too high. Pulsed wave Doppler (PW Doppler) is a type of ultrasound that uses the Doppler Effect to measure blood flow velocity. It does this by sending short pulses of ultrasound and then measuring the frequency of the returning sound waves. Pulsed wave Doppler is non-invasive and does not expose patients to ionizing radiation, making it a safe and effective diagnostic tool. Materials and methods: 60 patients attended the clinic. We measured systolic blood pressure by the traditional method using a sphygmomanometer and then using pulsed wave Doppler on the carotid artery. Results: The results displayed a significant correlation between systolic blood pressure measured by sphygmometer and peak systolic velocity. The results displayed a significant correlation between diastolic blood pressure measured by sphygmometer and end-diastolic velocity (edv). Conclusion: Ultrasound pulsed wave Doppler is a non-invasive diagnostic tool that utilizes sound waves to measure blood pressure. This technique is particularly useful for patients who are unable to tolerate the traditional cuff-based method, such as those with fragile skin or arterial access issues.
