Automatic noninvasive measurement of systolic blood pressure using photoplethysmography
BACKGROUND Automatic measurement of arterial blood pressure is important, but the available commercial automatic blood pressure meters, mostly based on oscillometry, are of low accuracy. METHODS In this study, we present a cuff-based technique for automatic measurement of systolic blood pressure, based on photoplethysmographic signals measured simultaneously in fingers of both hands. After in...
متن کاملIncreasing the Accuracy of Blood Hematocrit Measurement by Triplicate Wavelength Photoplethysmography Method
Background and objectives: The importance of continuous monitoring and rapid and accurate informing of changes in blood components (e.g., percentage of hematocrit [HCT]), especially in acute conditions, has motivated researchers to use non-invasive measurement methods. Therefore, this study aimed to evaluate the association between blood HCT and photoplethysmographic signal and the possibility ...
متن کامل[Home blood pressure measurement and ambulatory blood pressure measurement versus office blood pressure measurement].
PURPOSE To compare both home blood pressure measurement (HBPM) and ambulatory blood pressure monitoring (ABPM) with office blood pressure measurement (OBP); and also to compare the correlation between HBPM and OBP with LVMI (left ventricular mass index). METHODS Protocol 1--68 hypertensive patients (58 +/- 12 years, 37 females): a) self recorded blood pressure at home in the 7 days; b) record...
متن کاملComparison of Various Blood Pressure Measurement Techniques with Standard Office Based Blood Pressure Mesurement
Introduction: In order to control Hypertension, it is necessary to understand the methods of blood pressure measurement. Recent guidelines emphasize on employing appropriate blood pressure measurement techniques and white coat hypertension. Definition and methods of blood pressure measurement have changed in the American guideline based on SPRINT trial (Systolic Blood Pressure Intervention Tria...
متن کاملComparison of Systolic Blood Pressure Values Obtained by Photoplethysmography and by Korotkoff Sounds
In the current study, a non-invasive technique for systolic blood pressure (SBP) measurement based on the detection of photoplethysmographic (PPG) pulses during pressure-cuff deflation was compared to sphygmomanometry-the Korotkoff sounds technique. The PPG pulses disappear for cuff-pressures above the SBP value and reappear when the cuff-pressure decreases below the SBP value. One hundred and ...
