Effects of Deep Breathing on Blood Pressure Measurement in Healthy Subjects Luigi Yuri Di Marco, Dingchang Zheng, Alan Murray Newcastle University, Newcastle upon Tyne, UK stethoscope placed on the antecubital fossa of the arm wearing the cuff. Although the genesis of KS is still a matter of debate, several hypotheses have been proposed in the past decades [6-9], the most accredited being wall distension of the compressed artery, turbulent flow downstream of the compressed brachial artery, and cavitation. The aim of this study was twofold: i) to investigate the presence of a modulating effect of respiration on the Korotkoff sound amplitude; ii) to assess the effect of deep breathing on mean pulse rate (MPR) in the systolic-todiastolic blood pressure measurement, in healthy subjects.
Abstract The aim of this study was to investigate the effects of deep breathing on blood pressure parameters: systolic (SBP), diastolic (DBP) and pulse pressure, mean pulse rate (MPR), and the amplitude of Korotkoff sounds. Manual SBP and DBP were measured from 20 healthy subjects (age: 44±13 years) during normal (NB) and deep (DB) breathing. A chest magnetometer was used to acquire the respiratory depth, and an electronic stethoscope for the Korotkoff sound. All data were sampled at 2 kHz. MPR was derived from the oscillometric pulse waveform. For each oscillometric pulse, time-frequency analysis of the Korotkoff sound located the time of the peak energy (Tp), and Korotkoff sounds amplitude was defined as the maximum peak-topeak amplitude in the window TP±50ms. The respiratory rate was calculated from both the magnetometer (fR) and Korotkoff amplitude series (fK) for the period between the manually measured SBP and DBP, with a power spectral density resolution of 0.016 Hz in the physiological respiratory frequency range at rest. DB compared to NB increased respiratory regularity (quantified by spectral concentration) by 9±10% (mean±SD, p
