Use ultrasound to measure blood pressure

How to measure blood pressure with a bandage wrapped around the arm can pump air in not only old and inconvenient but also not provide enough information.

If you want to check for vascular diseases such as atherosclerosis, blood clots or aneurysms, surely the doctor needs to know how blood is flowing in an area inside the patient's arm. However, because the bandage temporarily stops blood circulation, it cannot be used in the patient's neck or in the person.

According to Gizmag , experts from the Eindhoven University of Technology (Netherlands) have discovered that ultrasound can be used in lieu of the above method, and it provides more information.

The Dutch team is testing blood pressure in a new way on humans, following successful carotid arterial tests of pigs.

With the new method, blood pressure can be measured without invasion anywhere on the body. By complex signal processing techniques, the system can show blood circulation and movement of blood vessel walls. Since then, it is possible to accurately identify blood pressure at that position.

This technology will allow users to monitor changes in blood pressure and blood flow at the same time as the heartbeat, providing information about what is happening in the ' downstream ' area of the site. measure. In addition, if a doctor measures blood pressure in a special position of the body, they can insert a catheter equipped with a pressure sensor.

Although the tests showed very promising results, the researchers said it would take years to introduce new blood pressure measurements into mass use.

The study was published in the journal Ultrasound in Medicine and Biology.
