El objetivo de este estudio es estimar las variaciones en las cifras de presión arterial, medidas en sujetos, utilizando diferentes esfingomanómetros (auscultatorio y oscilométrico).
Se evaluaron 5 esfingomanómetros, dos de tipo oscilométrico (omron HEM-412CINT) y tres de tipo auscultatorio (Random zero Hawksley & Sons. Las mediciones se realizaron en 25 mujeres y 6 hombres, por una enfermera experimentada y con el procedimiento estandarizado.
Los resultados mostraron que las variaciones fueron mayores en la presión sistólica, comparadas con la diastólica; de la misma manera en todos los casas la última medición con esfingomanómetro de mercurio siempre fue más parecida a la realizada con cualquiera de los esfingomanómetro.
La R2 en todos los casas fue alta y el coeficiente B, así como los intervalos de confianza mostraron una fuerte correlación entre las cifras registradas con el esfigmomanómetro de mercurio y los demás esfingomanómetros.
Al obtener la información sobre las variaciones, el personal de enfermería podrá ajustar las mediciones hechas con diversos esfingomanómetros, en diferentes poblaciones.
The blood pressure measurement procedure is a key aspect for an acute screening and control of blood hypertension,
which is considered a major problem both at a national and international level. Although the implementation of such
procedure takes place as part of the daily responsibilities of the nurse, it is of utmost importance to go beyond its simple
execution and to analyze its technical dimension in greater depth in order to provide the research team with parameters to
adjust the outcome figures according to a gold standard.
The objective of this study is to estimate the variations in the outcome figures resulting from the use of different methods in
the blood pressure measurement, such as diverse sphygmomanometers (the auscultatory and the oscillometric).
Five sphygmomanometers were evaluated, two of them of the oscillometric type, and the other three of the auscultatory
type (Random zero Hawksley & Sons). Measurements were carried out in 25 women and 6 men by a skilled and standardized nurse. Results showed that variations were higher in the systolic pressure as compared to the diastolic one; also, the
last measurement carried out with a mercury sphygmomanometer was always the closest to the remaining measurements
with other sphygmomanometers as compared to the first one.
In all cases, R2 was high and coefficient B, as well as confidence intervals, showed a strong correlation between the outcome figures from the mercury sphygmomanometer and those from other sphygmomanometers.
When obtaining information about variations, nursing staff will be able to adjust the measurements taken by different
sphygmomanometers in different localities.
