Objectives Mean arterial pressure at the upper arm is traditionally calculated by adding one-third of the pulse pressure to the diastolic pressure. We questioned the general validity of this formula. Methods We used previously recorded resting intrabrachial pressure and Riva–Rocci Korotkoff blood pressure measurements in 57 subjects (study A) and 24-h intra-arterial recordings obtained in 22 ambulant subjects (study B). Results In study A the intra-arterially measured ‘real’ mean pressure was… Expand
Arterial blood pressure measurement and pulse wave analysis--their role in enhancing cardiovascular assessment.
TLDR
Improved assessment of cardiovascular function in relation to treatment and management of high blood pressure will result from future developments in the indirect measurement of arterial blood pressure that involve the conventional cuff sphygmomanometer with the addition of information derived from the peripheral arterial pulse.

Non Invasive Assessment of Carotid and Femoral Arterial Pressure: Differences in Calibration Using Measured and Calculated Mean Brachial Pressure
TLDR
Investigation of the differences in carotid and femoral arterial pressure values after calibration using MAP calculated from brachial tonometry and from approximate formula found absolute error increases with increasing pulse pressure (PP) levels. Expand
Noninvasive assessment of central and peripheral arterial pressure (waveforms): implications of calibration methods
TLDR
Until more precise estimation methods become available, it is advisable to use 40% of brachial pulse pressure instead of 33% to assess MAP, and both carotid artery SBP and central SBP obtained via a transfer function are highly sensitive to the calibration of the respective carotids artery and radial artery pressure waveforms.

The noninvasive estimation of central aortic blood pressure in patients with aortic stenosis
TLDR
There is clinically acceptable agreement between noninvasive brachial pressure and directly measured central aortic pressure and the accuracy of noninvasively estimated subendocardial viability ratio was substantially improved by recalibration of radial arterial waveforms using corrected ejection time. Expand
Arterial pressure: agreement between a brachial cuff-based device and radial tonometry
TLDR
Cuff-based devices show promise to simplify the measurement of central blood pressure, whilst maintaining a similar fidelity to tonometry, which could lead to improved adoption of estimates of central BP in clinical practice. Expand
Estimation of Mean Radial Blood Pressure in Critically Ill Patients
If not estimated by a measuring device, the mean arterial pressure (MAP) can be approximated from the measured systolic (SBP) and diastolic blood pressure (DBP) by applying a traditional formulaExpand
Effects of gravity-induced upper-limb blood pressure changes on wave transmission and arterial radial waveform
TLDR
Findings provide a rationale for recommending to keep the upper limb at the heart level during radial waveform assessment and generate opposite, profound changes in rAIx, and major artifactual changes in aAIx. Expand
Which Mechanisms Determine Blood Pressure?
Blood pressure (BP) can be conceptually viewed as oscillations between two extremes (systolic blood pressure [SBP] and diastolic blood pressure [DBP]), the axis being mean BP (MBP) and the amplitudeExpand
Rule of thumb to calculate mean arterial pressure at the brachial artery level.
TLDR
The shape of the pressure wave is not available during routine BP measurements at the upper arm, so a simple textbook formula is generally used in which one-third of the pulse pressure is added to diastolic pressure. Expand
Mean arterial pressure estimated by brachial pulse wave analysis and comparison with currently used algorithms
TLDR
The estimation of mean arterial pressure (MAP) based on fixed formulas derived from SBP and DBP is unreliable and a more accurate estimation of MAP should be based on the pulse waveform analysis. Expand

Formula and nomogram for the sphygmomanometric calculation of the mean arterial pressure
TLDR
This article proposes a more precise formula for the estimation of mean arterial pressure and a nomogram for the calculation of MAP, using data from 150 patients who underwent cardiac catheterisation. Expand
Empirical estimates of mean aortic pressure: advantages, drawbacks and implications for pressure redundancy.
TLDR
TheAortic form factor was strongly influenced by age, aortic pressure and wave reflection, and an empirical formula that is consistent with mechanical principles in the arterial system gave a more precise estimate of MAP in the aorta of resting humans. Expand
Validation of a new formula for mean arterial pressure calculation: The new formula is superior to the standard formula
TLDR
Standard MAP calculations for MAP can easily be improved by inclusion of a heart rate factor, and the new formula showed a much closer correlation with the computer‐derived values for MAP. Expand
Systolic and Diastolic Blood Pressure, Pulse Pressure, and Mean Arterial Pressure as Predictors of Cardiovascular Disease Risk in Men
TLDR
It is suggested that average SBP, diastolic blood pressure, DBP, and MAP strongly predict CVD among younger men, whereas either average SBp or PP predictsCVD among older men. Expand

Pseudohypertension and the measurement of blood pressure.
TLDR
Riva-Rocci Korotkoff (RRK) blood pressure measurements may overestimate the intra-arterial pressure (IAP) in individual patients and the widely diverging prevalence of pseudohypertension described in the literature might be explained because of such different comparison techniques. Expand
