Comparison
Direct blood pressure measurement vs indirect blood pressure measurement
Design
Observational study with direct monitoring of Korotkoff sounds
Discrepancy between direct and indirect BP suggested; leaves open validation of Korotkoff accuracy in practice.
Direct monitoring of Korotkoff sounds from the brachial artex with vascular pressure, cuff pressure, and external sounds has been carried out. Recording of the internal sounds suggests a discrepancy between direct and indirect blood pressure measurement. Examples of spectrograms of the Korotkoff sounds near diastolic pressure are presented.
