Indications for the use of non-automatic sphygmomanometers are any

states that lead to an increase in blood pressure (in particular, the hypertonic

disease, the cardiovascular disease, the heart attack, or the stroke).

The Korotkov method distinguishes five phases of tones:

Phase I: the appearance of first permanent tones, the intensity of which

increases as the air is released from the pressure cuff. Indications of the

sphygmomanometer at the first tone corresponds to the level of systolic

arterial pressure.

Phase II: a "blowing" noise is added to the tones.

Phase III: intensity of tones and noise increases and reaches a

maximum.

Phase IV: a sharp weakening of the tones and disappearance of the

"blowing" noise. This phase can be used to determine the diastolic

arterial pressure in the patients who do not have Phase V tones (tones

are heard up to the zero mark of the sphygmomanometer).

Such patients can include children up to 12-14 years old, pregnant

women, people with hyperthyroidism, aortic insufficiency, high cardiac

minute output, and high body temperature.

Phase V: disappearance of tones. The indication of the sphygmomanometer

at the last tone corresponds to the diastolic blood pressure level*.
