Measured Parameters

  • Pulse rate;
  • Hemoglobin oxygen saturation;
  • Perfusion index (PI);
  • Vascular age;
  • Vascular stiffness;
  • Pulse wave type;
  • Relative duration of systole;
  • Stress level.

For each parameter, the device displays the numerical value and its evaluation in the chart with color-coded ranges. Color-coded ranges correspond to the following qualitative assessment results:

  • green – good condition;
  • yellow – satisfactory condition; increased risk of functional disorders, including cardiovascular;
  • red – poor condition; high risk of cardiovascular diseases. Detailed risk factor analysis by a specialist is necessary.

You should remember that the human body is an intricate system with a multitude of subsystems and their connections. Throughout life, with the change of seasons, during a diurnal cycle, with every inhalation and exhalation, the inner condition significantly changes. All these changes are reflected in the pulse character. In its usual state, the human body is not in equilibrium, as previously thought, but in a constant journey across the phase space of states, just like a river seeking its way within its floodplain. Diseases, stress, hard and good times shape the space where the body state travels. Heart rate monitoring can in some cases help identify critical problems or substantial deviations to take immediate measures—visit a specialist, adjust the sleep pattern or lifestyle.

The measured parameters can provide different angles of observation. And an improvement in one indicator is often accompanied by a reversal in the other.

Here are some typical cases:

  • Growing blood pressure and pulse rate increase together improve the supply of blood to small vessels, but reduce the index of vascular age.
  • Administration of vasoactive drugs contributes to vascular elasticity, reduces the strain on the heart, and puts the body in an uncomfortable state—entailing stress. After some time—it may be days, weeks—the body will find a new set of accustomed states, a new route for navigating them. The stress level will normalize.

If you need to evaluate long-term progress, conduct tests at the same time, in the same posture, and in the same condition. To evaluate the exact effect on your body (e.g., diet change, workout session, etc.), carry out two tests: one before the impact, the other after the impact. Assess the difference and draw a conclusion.


Spectral blood flow analysis helps determine how much hemoglobin in the body is in an oxygen-bound state. This indicator is critically important to people with chronic lung conditions.

Pulse wave

Provides qualitative assessment of your arteries. Identifies the time of maximum of direct and reflected volume pulse waves and to which phase of the cardiac cycle they correspond

duration of systole

The ratio of duration of systole to overall cardiac cycle duration (ED%) reflects the specifics of the cardiac cycle

Pulse rate

A critical parameter that allows evaluating the general shape of the cardiovascular system

Stress level

Status of the centers regulating the cardiovascular system. Also known as the heart rate variability index that is calculated from the analysis of pulse wave length distribution

Vascular stiffness

Assessment of arterial condition and leveling of blood pulsations generated by the left ventricle. This parameter helps evaluate the risk of capillary damage and disturbance of blood microcirculation in various organs.

Vascular age

Indicates the condition of smaller arteries responsible for optimal blood supply to organ tissues

Perfusion index (PI)

A technical parameter reflecting the desired signal the tracker can process.
