Introduction: Haemodynamic atrioventricular delay (AVD) optimisation has primarily focussed on signals that are not easy to acquire from a pacing system itself, such as invasive left ventricular catheterisation or arterial blood pressure (ABP). In this study, standard clinical central venous pressure (CVP) signals are tested as a potential alternative.
Methods: Sixteen patients with a temporary pacemaker after cardiac surgery were studied.

Background: Examples of group B red cells that react weakly or not at all with anti-B have been described. Subgroups of B such as B, B, B, and B are rare and are less frequently reported. We studied the frequency of subgroups of B in our healthy blood donor population and serologically characterized and differentiated these subgroups.

Red cell exchange is important to treat acutely ill sickle cell patients, but it is time-consuming. An automated red cell exchange technique using cell separators developed by different manufacturers helps in removal of sickled hemoglobin and improving blood viscosity. The use of these cell separators permits automated red cell exchange to be performed safely and smoothly with the isovolemic hemodilution.

Background And Objectives: Objective of the study is to explore the possibility of utilization of seven part fully automated hematology analyzer for enumeration of residual leukocytes (residual white blood cells [rWBCs]) in leukoreduced packed red cells (LR-PRCs) prepared from whole blood at a blood center as an alternate to the gold standard method, flow cytometry. In this study, we evaluate the performance characteristic of hematology analyzer against flow cytometry for the estimation of rWBCs in 39 LR-PRC units.
Materials And Methods: PRCs prepared from whole blood donations by 39 donors were leukoreduced and their volumes were noted.

Background: High titers of anti-A and anti-B are considered to be one reason for hemolytic transfusion reactions and ABO hemolytic disease in fetus and neonates. There is no consensus for critical ABO antibody titers to guide transfusion or transplant decisions. Implementation of ABO titer measurement can favor reduction in transfusion reactions in nongroup "O" recipients.
