`
`dissertation for the degree of Doctor of Medical Sciences,
`“Can the Ligation of the Abdominal Aorta During An—
`eurism in Groin Region Be Performed Easily and
`Safely?” While treating wounded soldiers who had an-
`eurysms, Korotkoff set a goal
`to find indications that
`would allow the surgeon to predict an outcome of ligation
`of arteries of the traumatized limbs, ie, to predict whether
`the limb would recover or die after surgery. While at-
`tempting to resolve this problem, he systematically lis-
`tened to the arteries to estimate the potential strength of
`arterial collaterals after a major vessel of the wounded
`limb had been ligated. He established that certain specific
`sounds could be heard during the decompression of the
`arteries. This specific phenomenon, known in world lit-
`erature as “Korotkoff sounds,” became the basis of the
`new method of blood pressure measurement.
`In his studies, Korotkoff used the apparatus proposed
`by Riva-Rocci“ in Italy in 1896 (Fig 2), which contained
`an arm-encircling inflatable elastic cuff, a rubber bulb to
`inflate the cuff, and a mercury sphygmomanometer to
`measure the cuff pressure. Riva-Rocci measured the sys-
`tolic pressure by registering the cuff pressure at which
`the radial pulse was obliterated as determined by palpa-
`tion. The palpation technique did not allow the measure-
`ment of diastolic pressure. Soon after Riva—Rocci’s tech-
`nique was described, Hill and Barnard7 in England in
`1897 reported an apparatus with an arm-encircling in-
`flatable cuff and a needle pressure gauge that allowed
`measurement of the diastolic pressure by the oscillatory
`method. This method used the oscillations transmitted to
`
`the gauge as the pulse wave came through the compressed
`artery. When the cuff pressure was reduced slowly from
`the suprasystolic pressure, the appearance of definitive
`oscillations denoted the systolic pressure, whereas the
`change from maximal oscillations to smaller ones de-
`noted the diastolic pressure.
`Similar to Riva-Rocci, Korotkoff used an inflatable
`sphygmomanometer cuff to obstruct arterial
`llow. His
`contribution was the discovery of a new, more accurate
`
`auscultatory technique to identify the times when the
`pressure in the cuff coincided with systolic and diastolic
`arterial pressures. When he examined patients who had
`damaged vessels, Korotkoff gradually compressed the ar—
`teries until the peripheral pulse disappeared. He also re—
`corded sphygmograms while simultaneously listening to
`the sounds in the part of the artery distal to the com-
`pressed arca. He determined that a totally compressed
`artery produced no sounds at all and that while the pres-
`sure in the artery was decreased gradually, certain sounds
`appeared that allowed one to judge the level of arterial
`pressure. 1'2
`t
`To measure blood pressure, Korotkoff applied an elas-
`tic, rubber cuff of the Riva-Rocci apparatus (Fig 2) on
`the middle third of the arm. The pressure in the cuff was
`increased until
`the blood supply to the periphery was
`completely stopped. Then the pressure in the cuff was
`decreased, and a stethoscope was used to listen to the
`pressure in the artery “directly below the cuff.”1 Once
`the pressure fell below a certain level, the first short tones
`could be heard; this indicated the passage of the first pulse
`wave along the artery below the cuff. The manometer
`reading at which the first tone appeared corresponded to
`the systolic pressure. With a further decrease in pressure
`in the cuff, the tones were replaced by murmurs that were
`followed in turn by second tones. Finally, all the sounds
`disappeared. The moment all sounds subsided, according
`to Korotkoff, blood was flowing freely through the arter-
`ies. The diastolic pressure in the artery at that moment
`slightly exceeded the pressure in the cuff, and the ma—
`nometer reading at the moment the sounds disappeared
`corresponded to the diastolic pressure.‘
`Simultaneous auscultation and palpation of the com-
`pressed artery revealed the difference in the cuffpressures
`for the appearance of sounds and the formation of the
`pulse wave in a segment distal to the compressed area.
`The first sounds appeared at the cuff pressure, which was
`10 to 12 mm Hg higher than the pressure at which the
`palpable pulse was produced, because generation of the
`pulse required some filling of the vessel.1
`Korotkoff considered the tones and murmurs in the
`
`vessel to be compression sounds. He thought the tones
`were caused by the rushing “of a minuscule part of the
`pulse wave” through the compressed area during a very
`short time interval. Also, vibrations of the “unsticking”
`

`cuff was approximately 1/2 arshin (35.56 cm) and the width was

`
`vessel walls contributed to the production of the tones.
`Korotkoff believed that the sound phenomenon depended
`on the elastic properties of the arterial walls.
`To prove the local generation of sound, Korotkoffper-
`formed a series of canine experiments. He reported the
`results of these experiments at a scientific seminar on
`December 13, 1905.8 Experiments demonstrated that
`sounds heard during the compression of vessels did not
`originate from the heart or the semilunar aortic valves, as
`was hypothesized by some of his critics. In one of the
`experiments, he placed a T—shaped cannula into an ex-
`posed femoral artery. The vertical branch ol‘ the cannula
`was connected to a container filled with saline. The artery
`was ligated proximal to the cannula and compressed by
`the cuff distal to the cannula. As pressure in the saline
`changed from 40 to 100 mm Hg,
`the wave of liquid
`passed through the vessel; the sounds produced iirst were
`tones, followed by murmurs, and then the sounds disap-
`peared. Thus, the experiments demonstrated that the K0-
`rotkoff sounds originated at the site of vessel compres—
`sion.8 Korotkoff’s presentation was highly praised by
`Prof M.V. Yanovskiy. He stated that he was in complete
`agreement with Korotkoff’s
`results:
`“. . .with this
`method, I believe, we will achieve quite accurate results
`.
`.
`.
`. I have to say that through your observations, you
`have demonstrated your talent and sharpness. You have
`noticed the fact that many other researchers who have
`been working on this problem missed.”8“"5°”""“’"’
`Yanovskiy’s clinic produced many studies in support
`of the auscultatory method of measurement of blood pres-
`sure. One of the earliest serious studies was the work by
`Krilov, “Determining Blood Pressure by Using the Sound
`Method of Doctor Korotkoff,”9 which was completed on
`the advice and under the supervision of Yanovskiy. The
`reports presented methods of study, described the types
`of sounds during the termination of the occlusion of the
`arterial vessel, and analyzed the sounds and the reasons
`for their generation and change.
`Later research studies by Krilov, Vesternik, Lebedev,
`Lang, and Mansvetova showed a close correlation be-
`tween arterial pressure measurements by Korotkoff’s
`method and measurements by use of other methods (Rek-
`lrnghausen, Pal, direct invasive measurements, etc).4'9‘11
`The method of measurement of blood pressure in-
`vented by Korotkofi’ quickly received wide recognition
`
`and became a standard medical procedure?5 This method
`played an important role in the study of various forms of
`disturbance of vascular tone and influenced our under-
`
`standing ol’ the etiology, pathogenesis, and treatment of
`hypertension. This method also made it possible to re-
`search the functioning of the cardiovascular system under
`normal conditions and during various diseases.
`Introduced in 1905, the simple and accurate Korotkoff
`method of measuring blood pressure has been used by
`physicians, nurses, researchers, and paramedics around
`the world throughout this century. Korotkoff’s method
`certainly will still be used extensively in the 21st century.
