blood pressure measurement
separated pressure sensors - Opis:
- Information about blood pressure at the inflow and outflow connectors as well as inside a Ventricular Assist Device (VAD) supplemented with information about pressures inside the pneumatic part enables to adjust operational parameters of the VAD in the optimum manner. Practical implementation of a method that makes it possible to measure blood pressure at plurality of points is a really sophisticated task in terms of technical and technological issues. On one hand it is mandatory to assure appropriate metrological properties of the entire measurement path, on the other hand the measuring transducers must be reliably separated from blood. Internal surfaces of these VAD parts that come in direct contact with blood must be smooth and uniform; it is extremely essential due to a risk of blood coagulation on any unevenness of surfaces. The paper presets the solution for measurements of blood pressure inside the VAD, where the suggested solution meets the assumed metrological criteria as well as very stringent safety requirements.
