Why the BPLab monitor doesn use an auscultatory channel (Korotkoff method)?
The manual method of blood pressure measurement by Korotkoff sounds is the main diagnostic and therapy’s effectiveness estimation method for blood pressure pathology inside clinical environment. However application of auscultatory technique in ambulatory monitoring has significant drawbacks and limitations: very high sensitivity to microphone’s position over the artery and the requirement of a direct contact with patient’s skin. As the experience shows during ambulatory monitoring microphone position and direct contact with patient’s skin requirement is often violated and all that makes accurate blood pressure measurement impossible and auscultatory high-accurate technique ineffective. The BPLab ambulatory blood pressure monitor applies oscillometric technique of BP measurement. We managed to create a high-accurate algorithm of BP measurement(in full conformity with ESH-2001 International Protocol).
