The coagulation system is activated by a reduction of the central blood volume during orthostatic stress and lower body negative pressure suggesting that also a blood loss enhances coagulation. During bleeding, however, the central blood volume is supported by fluid recruitment to the circulation and redistribution of the blood volume. ...

Subtracted blood volume spectrometry (SBVS) can eliminate the background information in near infrared spectroscopy (NIRS) noninvasive biochemical sensing. However, the spectrum obtained by this method is accompanied by serious noises which are to the disadvantage of the calibration models. Empirical mode decomposition (EMD) was applied to restrict the noises in ...

Hyporesponders to erythropoietin-stimulating agents (ESAs) have been associated with an increased subsequent risk of death or cardiovascular events. We hypothesized that subjects who are hyporesponsive to erythropoietin alfa would have higher plasma volumes and lower red cell deficits than subjects who are responsive to therapy. As part of a prospective, single ...

Finite-time transport between distinct flow regions is of great relevance to many scientific applications, yet quantitative studies remain scarce to date. The primary obstacle is computing the evolution of material volumes, which is often infeasible due to extreme interfacial stretching. We present a framework for describing and computing finite-time transport ...

Leukapheresis is a common procedure for hematopoietic cell transplantation in adults. The main challenge in applying this procedure to human infants and small monkeys is the large extracorporeal blood volume (165 mL on average) necessary for priming the apheresis machine. This volume represents greater than 50% of the total circulating ...

Maintaining cardiac preload throughout the perioperative period is a generally accepted target. As perioperative fasting is believed to cause intravascular hypovolaemia it traditionally triggers aggressive preemptive intravenous fluid infusion. Physiology suggests that extracellular losses via urinary output and evaporation decrease the extracellular compartment. Representing a relevant part of the latter, ...
