Why the study?
Common noninvasive blood pressure measurement techniques have clinical limitations, with auscultatory sphygmomanometry limited by noise artifacts in automatic variants and automatic oscillometry having low accuracy.
Do cuff-based electronic techniques utilizing PPG or electronically recorded Korotkoff sounds improve the accuracy of systolic blood pressure measurement compared to the auscultatory Korotkoff-based technique?
