“…A greater proportion of dissolved O 2 can be reached with a higher inspiratory fraction of O 2 (FiO 2 ), which may be useful in acute anaemia. 2 and starts to decrease with any further reduction in DO 2 . The DO 2 , at which VO 2 starts to decrease, is called critical DO 2 (DO 2 crit).…”

“…During acute blood loss replaced by crystalloids and colloids, Hb falls and the physiological reaction is an increase in CO, an increase in EO 2 and right shift of the Hb dissociation curve [1]. Decrease in blood viscosity and sympathetic stimulation result in an increase in stroke volume [2][3][4].…”

“…Assim como em humanos, parâmetros clínicos são mais importantes do que resultados laboratoriais na decisão (PEREIRA; RAMALHO, 2001;SIGRIST, 2008). Uma forma de estudar experimentalmente a anemia e chegar a um valor de hemoglobina crítica, ou seja, um valor abaixo do qual a hipóxia tecidual não é tolerada, é por meio da diluição intencional do sangue (hemodiluição), uma técnica na qual uma quantidade de sangue é removida do indivíduo, porém o volume é mantido através da infusão simultânea de soluções cristalóides ou coloides e posteriormente o sangue pode ser reinfundido (GEHA; BAUE, 1978;JAMNICKI et al, 2003;SHANDER, 2004;CHAMPION, 2008). Sob as condições de uma anemia aguda normovolêmica (hemodiluição), o consumo de O2 pelos tecidos (VO2) é mantido pelo aumento do débito cardíaco e pelo aumento da liberação de oxigênio para os tecidos (aumento da síntese 2,3-DPG).…”

“…Cardiac valve surgery is considered a major surgery with a high chance of hemorrhage and extracorporeal circulation dilution [4] Normovolemic hemodilution is a type of autologus blood transfusion i.e, percentage of blood volumeis withdrawn from the patient and infusion of acellular fluids in order to maintain the volume and retransfuse back the same amount in same patient [5,6] . This procedure will make the patient anemic, although patient will remain normovolemically and hemodynamically stable [7] .…”
