内容記述 | A new method is presented for the indirect measurement of systolic (SBP) and diastolic blood pressure (DBP) in the radial artery. We use the volume-oscillometric method with a wrist cuff and then, utilizing the photo-plethysmograph (PPG) signal together with cuff pressure measurements, we derive pressure-volume curves (PVC). The principle of this method, named “PVC inflection-point method”, is to identify the indirect SBP and DBP using the inflection-points of envelope curves overlaying respectively the lower and upper points of the photo-plethysmographic pulsation signals superimposed on an arterial volume signal during the volume-oscillometric procedure. The accuracy of the method was evaluated by comparison with measurements from arterial catheterization in two healthy subjects. During the test procedure, a prototype PPG sensor for the PVC inflection-point method was attached to the left wrist, and arterial catheterization of the right radial artery for was performed to obtain simultaneous blood pressure recordings. The Bland-Altman plots for the comparative analysis showed good agreements between the two methods for both SBP (+2.3±7.7 (mean±S.D.) mmHg) and DBP (-1.8±6.4mmHg) measurement. We conclude that the proposed PVC inflection-point method appears promising to determine indirect SBP and DBP values with appropriate accuracy for convenient and practical use. | |||||
