![]() Therefore, the correct identification of the phase IV of korotkoff sounds is the key to accurately measure the blood pressure of this particular group of people. children under 12 years old, pregnant women, elderly, severe anemia, hyperthyroidism, aortic insufficiency, etc.), reading of the diastolic pressure at the IV phase of korotkoff sounds is required. However, for some special populations (e.g. There are several papers and patents that propose methods that can automatically recognize these two korotkoff sounds. using neural networks, statistical classifiers, expert systems or fuzzy systems involving training the classification deviceįor most adults, the cuff pressures corresponding to the first and last heard korotkoff sounds are recorded as systolic and diastolic pressures, respectively.
