Raised lactate levels in blood
WebbLactate levels are commonly evaluated in acutely ill patients. used in the context of evaluating shock, lactate levels can be elevated for many reasons. While tissue hypoperfusion may be the most common cause of elevation, many other etiologies or contributing factors exist. Clinicians need to be aware of the many potential causes WebbLactate concentrations and lactate threshold. Blood lactate levels as a function of workload for the hydrated and dehydrated trials are presented in Figure 1.There was a significant shift of the lactate threshold to a lower percent of V̇O 2max with dehydration (72.2 ± 1.1 and 65.5 ± 1.9% for hydrated and dehydrated trials, respectively;P = 0.03). ). …
