About the technology
simply measure your blood pressure
The technology developed and patented by OSTAR is the heart spectrum technolgy. The technology analyses the data collected from the blood pressure measurement and results in useful indications for the healthy status of the heart.
The OSTAR heart spectrum blood pressure monitor applies the oscillometric method to measure the blood pressure and pules. The sensor inside the OSTAR heart spectrum blood pressure monitor detects the oscillations of the blood flow (the pulse) by the connected cuff on the upper arm of the user and save the data in time domain pressure wave. The time domain pressure wave is then transformed into a frequency domain wave by means of FFT (fast Fourier Transformation).
After the FFT transformation, the frequency wave shows the main peak frequency. When a different peak frequency is identified from the main peak frequency, this abnormal peak frequency will be defined as heart noise and will be quantised as the heart spectrum index. The quantitative calculation of heart noise is determined by the number of abnormal peak frequencies appeared, applying the proportional parameter determined by the clinical test results and after the background noise is removed.
