The heart spectrum technolgy is a patented analysis technology developed by OSTAR Meditech Corp., Taiwan, by analyse the data collected on a blood pressure measurement to provide information about the healthy status of the heart. The results of the analysis are presented by three useful indexes that give an overview of the healthy status of your heart each time you measure your blood pressure.
The OSTAR heart spectrum blood pressure monitor is a unique meaurement equipment on the market that displays much more information than just an indication of irregular heartbeat (arrhythmia).
The OSTAR heart spectrum blood pressure monitor will collect the measurement data throughout the measurement process. After completing the measurement, the CPU inside the OSTAR heart spectrum blood pressure monitor will use the heart spectrum technology to transmit the measurement data and to further analyse the data to find out if there are any abnormal frequencies (heart noises) discovered in the measurement period.
Using the heart spectrum technology, the OSTAR heart spectrum blood pressure monitor is able to identify heart noises caused by irregular heartbeats, not completely closed or prolapsed heart valves or abnormal vibrations of blood flow in the coronary artery.
The patented technology of OSTAR provides useful references for personal health management at home and helps you to take precautionary actions for the early diagnose potential heart diseases.
automatic correction and calibration technology
Each time the OSTAR heart spectrum blood pressure monitor is turned on it performs an internal check of the measurement accurancy according to the surrounding enviromental conditions such as temperature, humidity, air pressure, height , latitude, etc. and its components status. If any difference outside the tolerance of the built-in setting is found, the OSTAR heart spectrum blood pressure monitor will conduct an correction accordingly and calibrates the equipment to re-establish the measurement accuracy.
The individual settings of personal control target for
blood pressure and pulse
Although the blood pressure readings 120mmHg/80mmHg are recognised as the optimal blood pressure readings, but due to difference in age, health situation and physical conditions, each person would have different ideal blood pressure readings to maintain.
With the settings of the alarm range of the OSTAR heart spectrum blood pressure monitor, once any measured reading of your blood pressure or your pulse exceed the control target your set, the reading will be displayed in flashing mode, so that you see the warning instantly.
When using the OSTAR HK-809 heart spectrum blood pressure monitor for blood pressure measurement, the equipment will first inflate the cuff until the preset maximum pressure (around 180 mmHg) is reached. Then the equipment will start to slowly deflate the cuff. During the deflating, the OSTAR HK-809 heart spectrum blood pressure monitor will measure the systolic blood pressure and the diastolic blood pressure.
If for any reason the correct blood pressure values can't be obtained during the deflating, the OSTAR HK-809 heart spectrum blood pressure monitor will automatically inflate the cuff again to a higher pressure (around 200 mmHg), then deflate the cuff again to complete the measurement.
With this function, the OSTAR blood pressure monitor can always obtain the correct readings of the blood pressure from the measurement.
Use of the
OSTAR heart spectrum technology
The heart spectrum technolgy is a patented analysis technology developed by OSTAR Meditech Corp., Taiwan, by analyse the data collected from a blood pressure measurement to provide information about the healthy status of the heart.
After the measurement, the collected measurement data is transformed into a frequency domain wave by means of FFT (fast Fourier Transformation). The frequency domain wave shows the main peak frequency. Clinical trials find that the main frequency peaks of the tranformed normal blood pressure measurement data is displayed with three identifiable regions. 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 sum of heart noise in the first frequency region is the value of the heart spectrum index I1 , and the sum of heart noise in the second frequency region is the value of the heart spectrum index I2, and the sum of heart noise in the third frequency region is the value of the heart spectrum index I3.
Clinical trials also indicate that the heart spectrum index I1 is the noise index of arrhythmia, and the heart spectrum index I2 is the noise index of the heart valve, und the heart spectrum index I3 is the noise index of the coronary artery.
ensures that the OSTAR heart spectrum blood pressure monitor shows the same reliable accurate measurement data in every mensurement.
After each measurement, the OSTAR heart spectrum blood pressure monitor displays two groups of measurement data:
Systolic blood pressure
Diastolic blood pressure
Hear spectrum index I1
Hear spectrum index I2
Hear spectrum index I3
Range and accuracy of the blood pressure measurement
30 – 240 mmHg, scale: 1 mmHg
accuracy: ±3 mmHg oder 2% of the measured values
Range and accuracy of the pulse measurement
30 – 160 beats per minute, scale: 1 beat per munite
Accuracy: ±2 beats per minute oder 2% of the measured values
How does it work?
The non-invasive auscultatory and oscillometric measurements are simpler and quicker than invasive measurements, require less expertise, have virtually no complications, are less unpleasant and less painful for the patient. However, non-invasive methods may yield somewhat lower accuracy and small systematic differences in numerical results. Non-invasive measurement methods are more commonly used for routine examinations and monitoring.
The oscillometric method was first demonstrated in 1876 and involves the observation of oscillations in the sphygmomanometer cuff pressure which are caused by the oscillations of blood flow, i.e., the pulse.
The first fully automated oscillomettric blood pressure cuff was made available in 1981. It uses a sphygmomanometer cuff, like the auscultatory method, but with an electronic pressure sensor (transducer) to observe cuff pressure oscillations, electronics to automatically interpret them, and automatic inflation and deflation of the cuff. The pressure sensor should be calibrated periodically to maintain accuracy.
