What is the OSTAR's heart spectrum technology?
The heart spectrum technology is a patented analysis technology developed by OSTAR Meditech Corp., Taiwan.
Using this technology to analyse the measurement data collected from a blood pressure measurement will provide useful information about the healthy status of the heart. The results of the analysis are presented by three indexes, heart spectrum index I1, I2 and I3, that provide a numerical overview of the healthy status of your heart each time you measure your blood pressure.
Clinical trials confirmed that the heart spectrum index I1 obtained by the analysis of the heart spectrum technology 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.
What is the OSTAR heart spectrum index I1?
The OSTAR heart spectrum index I1 is a numerical information about the irregular heart beats obtained by using the OSTAR heart spectrum technology which analyse the measurement data collected from a blood pressure measurement.
The heart normally has a certain heartbeat frequency (heart rate), this is a normal phenomenen. The heart rate can vary according to the body's physical needs and will also be modulated by a myriad of physical/external factors. The heart rate is usually equal or close to the pulse measured at any peripheral point. If the heart beats faster or slower than the main heart rate, these conditions are called the heart Arrhythmia.
When measuring blood pressure with the OSTAR heart spectrum blood presure monitor, if heart Arrhythmia was detected, the analysis of the measurement data applying the heart spectrum technology will identify the number of happenings of such abnormal heart beats and display it as heart spectrum index I1.
What is the meaning of OSTAR heart spectrum index I1?
The OSTAR heart spectrum index I1 is a numerical information about the irregular heart beats obtained by using the OSTAR heart spectrum technology to analyse the measurement data collected from a blood pressure measurement.
For normal heart beats, the value of the OSTAR heart spectrum index I1 is zero (0). If the heart arrhythmia was identified only once, the value of the index I1 is 1. If the heart arrhythmia was identified twice, the value of the index I1 is 2, and so on. The highest value of the index I1 is 20.
What is the OSTAR heart spectrum index I2?
The OSTAR heart spectrum index I2 is a numerical information about the conditions of heart valves obtained by using the OSTAR heart spectrum technology to analyse the measurement data collected from a blood pressure measurement.
When the heart beats once, the valves are opened and closed twice. If any of the heart valves does not close completely or prolapse the blood flow will generate abnormal vibrations.
When measuring blood pressure with the OSTAR heart spectrum blood presure monitor, if abnormal vibrations of the blood flow were detected, the analysis of the measurement data applying the heart spectrum technology will identify the number of happenings of such abnormal vibrations and display it as heart spectrum index I2.
What is the meaning of OSTAR heart spectrum index I2?
The OSTAR heart spectrum index I2 is a numerical information about the conditions of heart valves obtained by using the OSTAR heart spectrum technology to analyse the measurement data collected from a blood pressure measurement.
For smooth blood flow without any abnormal vibration, the value of the OSTAR heart spectrum index I2 is zero (0). If the abnormal vibration was identified only once, the value of the index I2 is 1. If the abnormal vibration was identified twice, the value of the index I2 is 2, and so on. The highest value of the index I2 is also 20.
What is the OSTAR heart spectrum index I3?
The OSTAR heart spectrum index I3 is a numerical information about the conditions of coronary arteries obtained by using the OSTAR heart spectrum technology to analyse the measurement data collected from a blood pressure measurement.
When the heart beats the blood is pushed out of the heart, while the aortic valve is opened, and flows to the aorta and the rest of the body but not flows to the coronary arteries. Only when the aortic valve is closed, will the blood flow into the coronary arteries then. When the coronary arteries are normal, there will be no abnormal vibration generated by the blood flow.
When measuring blood pressure with the OSTAR heart spectrum blood presure monitor, if abnormal vibrations of the blood flowin the coronary arteries were detected, the analysis of the measurement data applying the heart spectrum technology will identify the number of happenings of such abnormal vibrations and display it as heart spectrum index I3.
What is the meaning of OSTAR heart spectrum index I3?
The OSTAR heart spectrum index I3 is a numerical information about the conditions of the coronary arteries obtained by using the OSTAR heart spectrum technology to analyse the measurement data collected from a blood pressure measurement.
For smooth blood flow in the coronary arteries without any abnormal vibration, the value of the OSTAR heart spectrum index I3 is zero (0). If the abnormal vibration was identified only once, the value of the index I3 is 1. If the abnormal vibration was identified twice, the value of the index I3 is 2, and so on. The highest value of the index I3 is 10.
What is the OSTAR's automatic correction and calibration technilgy?
The automatic correction and calibration technology is a patented technology developed by OSTAR Meditech Corp., Taiwan.
Using this technology every time the OSTAR heart spectrum blood pressure monitor is turned on, the equipment started an internal testing sequence to verify the measurement accurancy in accordance with 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 settings 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 automatic correction and calibration technology ensures that every measurement made by OSTAR heart spectrum blood pressure monitor is of the same accurancy, regardless of when and where the measurement is performed.
What is calibration? And why dose a blood pressure monitor need to be calibrated?
The calibration was the precess that minimized measurement uncertainty to ensure the accuracy of the measurement equipment. The calibration quantified and controls errors or uncertainties within an acceptable level during the measurement process.
Calibration is important wherever measurement results are important for user, so that the user can rely on that and then fulfill their purpose for monitor, control and etc. That's why every measurement equipments were calibrated before they were shipped out to the customers.
After a certain period of use, the results and accurancy of a measurment equipment tend to "drift", especially when using certain technologies or measuring certain parameters such as temperature and humidity. To ensure the results measured are accurate and reliable, and the measurement itself is repeatable, there is a constant need to maintain and calibrate the measurement equipments throughout their life of service.
