Abstract
La presión arterial (PA) es un parámetro fundamental en el seguimiento y tratamiento de enfermedades cardiovasculares. Existen dos métodos principales para su medición: el método auscultatorio, que requiere el uso de un estetoscopio y un esfigmomanómetro, y el método oscilométrico, empleado por dispositivos automáticos que detectan las oscilaciones en el brazalete durante la desinflación.
Este trabajo de fin de máster compara ambos métodos en términos de repetibilidad y concordancia diagnóstica. Para ello, se diseñó un estudio observacional con adultos voluntarios, en el que se recogieron mediciones repetidas de PA mediante técnicas auscultatoria y oscilométricas bajo condiciones controladas. También se registraron variables contextuales como edad, sexo, índice de masa corporal, actividad física y dieta.
Aunque el método auscultatorio se considera el estándar clínico, los dispositivos oscilométricos, ampliamente utilizados en la actualidad, presentan limitaciones que pueden provocar discrepancias diagnósticas relevantes, especialmente en ciertos perfiles de pacientes. Este estudio busca aportar evidencia que contribuya a una mejor comprensión de estas diferencias y al uso más informado de los dispositivos de medición en la práctica clínica.
Blood pressure (BP) is a key parameter in the monitoring and treatment of cardiovascular diseases. There are two primary methods for its measurement: the auscultatory method, which involves the use of a stethoscope and a sphygmomanometer, and the oscillometric method, employed by automated devices that detect cuff oscillations during deflation. This master’s thesis compares both methods in terms of repeatability and diagnostic agreement. An observational study was conducted with adult volunteers, in which repeated BP measurements were obtained using both auscultatory and oscillometric techniques under controlled conditions. Contextual variables such as age, sex, body mass index, physical activity, and dietary habits were also recorded. Although the auscultatory method is considered the clinical gold standard, oscillometric devices—widely used in current practice—present limitations that may lead to significant diagnosti discrepancies, particularly in certain patient profiles. This study aims to provide evidence that enhances the understanding of these differences and supports more informed use of BP measurement devices in clinical settings.
