Shock lactate
WebShock status, such as cardiogenic or septic shock, is an important source of lactate production. Acidic conditions caused by lactic acidosis depress cardiac function and decrease the response of vasopressors. In contrast, sodium bicarbonate, which is used to correct metabolic acidosis, may aggravate lactic acidosis and increase mortality (9). Web24 Nov 2024 · Lactate >4 mM suggests shock, but this has a broad differential diagnosis. Lactate usually doesn't reflect oxygen deficiency, but rather endogenous epinephrine in response to physiologic stress. This explains why lactate can be normal in shocked patients who have inadequate sympathetic nervous function. High lactate level is worrisome. This ...

In general, the lactate level of 2.0-2.5 mmol/L is considered elevated, however when the lactate level raised > 4mmol/L it is considered 'high' with corresponding lactic acidosis (pH < 7.35).
WebSerum bicarbonate is usually low, and serum and blood lactate levels increase. As shock progresses, metabolic acidosis worsens, and blood pH decreases. Early hypoxemic respiratory failure leads to a decreased PaO2:FIO2 ratio and sometimes overt hypoxemia with PaO2 < 70 mm Hg.
