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… 

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.

A preliminary evaluation of the mean arterial pressure as measured by cuff oscillometry.

TLDR
The results show that, over a wide range of cuff pressures, the oscillometric MBP predicts aortic pressure better than the SBP or DBP do, with a better correlation coefficient.

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.

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.

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.

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 formula

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.

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 amplitude

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.

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.

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.

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.

Reconstruction of brachial artery pressure from noninvasive finger pressure measurements.

TLDR
BAP waves can be reconstructed from noninvasive finger pressure registrations when finger pressure waves are corrected for pulse wave distortion and individual pressure gradients.

Feasibility of ambulatory, continuous 24-hour finger arterial pressure recording.

TLDR
Portapres provides for the first time continuous 24-hour, noninvasive ambulatory blood pressure waveform monitoring and offers real and obvious advantages over current nonin invasive and invasive devices.

Disparities Between Aortic and Peripheral Pulse Pressures Induced by Upright Exercise and Vasomotor Changes in Man

TLDR
It is concluded that estimates of stress on aortic and cerebral vessel walls and central baroreceptors would be grossly overestimated by use of peripheral pulse pressures.

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.

The meaning of the point of maximum oscillations in cuff pressure in the indirect measurement of blood pressure--part ii.

TLDR
The cuff pressure for maximal oscillations appears to provide a reasonable estimation of the true mean arterial pressure provided compression chamber air volume is kept small.
