Criterios de exclusión para la donación en un banco de sangre de Morelos

SAMARA MACHUCA FIGUEROA (2023, [Otro, Trabajo terminal, especialidad])

El diferimiento de la donación es el periodo de tiempo que un individuo no es apto para

donar sangre, basado en criterios que buscan su seguridad y la del paciente que recibirá la sangre. La donación es la única forma de obtención de elementos formes de uso terapéutico. Empleando la teoría de “Logro de Objetivos” de Imogene King, se busca mejorar la interacción enfermera donador, para disminuir los diferimientos.

Blood donor deferral period is the length of time that an individual is not elegible to donate blood based on criterio in place to protect the health and safaty for the patiente who recives the blood. Donation is the one way to get blood for therapeutic use. With Imogene King’s theory of goal attaiment, the interaction nurse-donor, would be better to decrease donor deferral.

Variability of Microcirculation Detected by Blood Pulsation Imaging

Alexei Kamshilin (2013, [Artículo])

The non-invasive assessment of blood flow is invaluable for the diagnostic and monitoring treatment of numerous vascular and neurological diseases. We developed a non-invasive and non-contact method of blood pulsation imaging capable of visualizing and monitoring of the two-dimensional distribution of two key parameters of peripheral blood flow: the blood pulsation amplitude and blood pulsation phase. The method is based on the photoplethysmographic imaging in the reflection mode. In contrast with previous imaging systems we use new algorithm for data processing which allows two dimensional mapping of blood pulsations in large object's areas after every cardiac cycle. In our study we carried out the occlusion test of the arm and found (i) the extensive variability of 2D-distribution of blood pulsation amplitude from one cardiac cycle to another, and (ii) existence of the adjacent spots to which the blood is asynchronously supplied. These observations show that the method can be used for studying of the multicomponent regulation of peripheral blood circulation. The proposed technique is technologically simple and cost-effective, which makes it applicable for monitoring the peripheral microcirculation in clinical settings for example, in diagnostics or testing the efficiency of new medicines. © 2013 Kamshilin et al.
