BLOOD OXYGEN CONCENTRATION ANALYZER, AND METHOD AND APPARATUS FOR MEASURING BLOOD PRESSURE VALUE BY ELECTROCARDIOGRAPH

摘要

PPROBLEM TO BE SOLVED: To provide a blood oxygen concentration analyzer and a method and an apparatus for measuring a blood pressure value by an electrocardiograph. PSOLUTION: The method for measuring the blood pressure value unerringly detects a periodic continuous changing waveform of blood oxygen in a cardio-artery pulsation by a blood oxygen concentration analyzer and the pulsation intervals of systolic pressure and diastolic pressure by the electrocardiograph, relates the pulsation intervals to the continuous changing waveform measured by the blood oxygen concentration analyzer, computes cross-sectional areas by relating the continuous changing waveform to the pulsation intervals of an electrocardiograms by using a micro-processor, converts them to the diastolic pressure and systolic pressure values by a saved calculation formula to achieve the accurate measurement of the blood pressure values (systolic and diastolic pressures).
