Indeterminate Control Diagrams as Health Control Tools

Abstract

In recent decades, the development of techniques that allow continuous or periodic blood pressure measurement, both systolic and diastolic, in different individuals has shown that it experiences spontaneous variations in 24 hours. The variability of blood pressure has been calculated based on the standard deviation, and it has been possible to determine that this, with significant differences between individuals, behaves in such a way that the systolic pressure is higher than the diastolic. It has also been reported that the fluctuation is more significant in hypertensive patients than in normotensive patients, as the level of indeterminacy exists. Control charts, as in classical statistics, use the upper limit of control (ULC) and lower limit of control (LLC) to contain the existing uncertainties in the variable, although it would be advantageous to verify it using ambulatory blood pressure monitoring. The prognosis can be improved by ensuring an increase in blood pressure control in high-risk patients. This study focuses on the variations to which the variable is exposed by a level of indeterminacy existing with neutrosophic statistics. It is obtained that adult patients have the greatest affectations of this disease, which is why they require greater control and medical attention, and more precise equipment to obtain a successful result.
