Accuracy of some algorithms to determine the oscillometric mean arterial pressure: a theoretical study.
2013
Methods Using a computer-based model, the accuracy of five algorithms was studied: maximum amplitude algorithm, 33 and 40% formulas calculating the mean arterial pressure from oscillometrically measured systolic and diastolic pressures, and two oscillation shape-based algorithms. We examined to which extent the tested algorithms were influenced by variations in four affective factors: pulse pressure, arterial pressure pulse shape index, and two shape indices (symmetry and steepness) of the artery–cuff pressure/volume relationship. Different ranges of variation of affecting factors were applied.
