For more than a hundred years, the once unknown Italian therapist made a great contribution to the development of medicine, inventing the method of measuring blood pressure using a special apparatus. However, modern scientists are not behind, offering instead of cuff and pump to use a fundamentally new methodology.
For almost three decades, all doctors and many patients who suffer from arterial hypertension use electronic devices to measure pressure, the principle of which is based on a method once invented by an Italian doctor who perpetuated his name – Shipion Riva Riva Riva Riva Riva).
At the heart of mercury tonometers (sphimonometers) of old samples and new more advanced automated devices with an electronic display are two elements: a cuff that covers the arm above the elbow, and the pump is a device that pumps air in the cuff. Moreover, this method also has disadvantages, among which the main thing is the discrepancy between the requirements of modern cardiology. In addition, the process of measuring pressure is quite long, which takes precious minutes, which in the account of a modern person.
Australian scientists were able to solve the problem who, at this stage, begin clinical trials of a fundamentally new method of monitoring of blood pressure, which they created. Estimated test duration – about two years.
In turn, researchers from the University of the Australian state of Queensland found their solution – they created a medical electronic “pencil”, with which you can measure the pressure.
All that needs to be done is to attach the device sensor to the wrist area from the inside (this is a place where doctors usually measure the pulse frequency in patients), after which the data of the central aortic systolic pressure (TSASD) and frequency are reflected after a few seconds after a few seconds. heart contractions. Scientists argue that the first of the listed indicators has greater accuracy in reflecting the condition of the patient’s cardiovascular system compared to the traditional measurement of pressure in the shoulder artery. As the results of the studies have shown, the difference between both indicators can be 20 and even 30 mm Hg in the same person.
In addition, there is another very important point. The fact is that some of the very common preparations for the treatment of hypertension can help reduce pressure in the shoulder artery, but at the same time increase CASD, and this phenomenon can cause a very serious consequences in the patient.
