Abstract
Background and objectives

There are discrepancies regarding how to measure blood pressure (BP). The goal of this study was to determine the differences between one automatic BP measurement and the mean of 3 automatic BP measurements.

Patients and method

Two patient populations were used. A sample population (n=1337) in which the measurement was performed by a nurse at the health center, and a consecutive series of patients (n=200) who had the measurement performed in front of the doctor in the office.

Results

The differences found between the first reading and the average of 3 determinations were small in both cases. In the population sample, BP levels ranged from 2.07 to 3.21mmHg, and in patients who had their BP levels measured in the presence of doctor, this value ranged from 2.71±3.82mmHg (systolic pressure), with minimal differences in diastolic BP levels.

Conclusions

Little difference was found between the first determination and the average of 3 automatic BP readings.

Resumen
Fundamento y objetivos

Existe discrepancia sobre cómo medir la presión arterial (PA). El objetivo de este trabajo fue estudiar la diferencia entre una determinación y la media de 3 determinaciones automáticas de la PA.

Pacientes y método

Se utilizan 2 poblaciones de pacientes: una muestra poblacional (n=1.337) en la que la medición se realiza por una enfermera en el centro de salud, y una serie consecutiva de pacientes en los que se realiza delante del médico, en la consulta (n=200).

Resultados

Las diferencias halladas entre la primera lectura y el promedio de 3 determinaciones son pequeñas en ambos casos. En la muestra poblacional oscila entre 2,07-3,21mmHg y en los pacientes en los que se determina en presencia del médico, es de 2,71±3,82mmHg en la sistólica, con mínimas diferencia en la PA diastólica.

Conclusiones

En la determinación automática de la PA, existe escasa diferencia entre la primera determinación y el promedio de 3 lecturas.
