Sounds of Korotkov

Dr. Doping tells about the basics of blood pressure measurement techniques, an infinite tone and pulse wave velocity. What affects the accuracy of the arterial blood pressure measurement? What is the cause of the noise, following the Korotkov? How to choose the perfect blood pressure monitor?

Korotkov is a high-frequency oscillations of the arterial wall and surrounding tissues that arise amid a wave of dramatic unfolding external clamping pressure vessel. tone frequency is determined by inertia and bending stiffness wall surrounding tissues, and thus it increases at a voltage of shoulder muscles. Infinite Tone - a rollover of the pulse wave, and it needs to perform one of two conditions: either a very steep pressure wave front, or should be very steep dependence of the rate of pressure drop, which happens in some pathologies.

If Korotkov’s method was in the 20s, 30s, 40s verified direct "blood" experiments, thrust sensor artery and directly measured the pressure, but now no one has neither the financial nor the organizational or ethical options is checked automatically blood pressure of the pressure.

How do they work? They do not listen to of Korotkov sounds. They measure the cuff pressure when the vibrations start there, something begins to oscillate, they secrete these oscillations. Now quite popular attempts to make devices that are more finely analyze the structure of the pulse wave. Perhaps there is some perspective. of Korotkov method is remarkable in that you do not make a bad patient, it is absolutely safe.
