Es un término muy utilizado en la literatura científico-técnica; sin embargo, no muy bien caracterizado. En el presente artículo se ofrece una aproximación teórica a la disponibilidad de sangre, sus componentes y factores determinantes; así como, se ofrecen algunos aspectos prácticos de su gestión dentro de los servicios de salud. La disponibilidad de sangre es una cualidad referida a la cantidad de unidades de sangre que se encuentran listos para ser utilizados en los pacientes que lo requieran en un momento determinado y para un área geográfica definida. Sus componentes principales son la oferta y la demanda de sangre. En la cadena transfusional se planifican, ejecutan y controlan varias actividades estrechamente vinculadas entre ellas y con el medio externo; lo cual le imprime un carácter multidimensional a la disponibilidad de sangre y un dinamismo peculiar a las actividades de donaciones, procesamiento y trasfusiones de sangre. Conocer las relaciones de dependencia que se establecen entre las partes de esta cadena logística, constituye elemento imprescindible para la gestión eficiente de los programas de sangre.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT The blood availability (BA) constitutes an essential element for universal access to transfusions and a priority for local health systems. It is a term widely used in the scientific-technical literature, however, not very well characterized. This article offers a theoretical approach to BA, its components and determining factors; as well as, some practical aspects of its management within the health services are offered. BA is a quality referred to the amount of blood units that are ready to be used in patients who require it at a given time and for a defined geographic area, its main components are the supply and demand for blood. In the transfusion chain, various activities closely linked to each other and to the external environment are planned, executed and controlled; which gives a multidimensional character to the BA and a peculiar dynamism to the activities of donations, processing and blood transfusions. Knowing the dependency relationships that are established between the parts of this logistics chain is an essential element for the efficient management of blood programs.]]></p></abstract>
