Lactic acidosis physical examination

There are no specific signs to determine lactic acidosis but its cause may be evaluated via thorough examination.

• Look for signs of hypovolemic, cardiogenic, septic or toxic shock.
• To classify the lactic acidosis look for signs of tissue hypoperfusion such as hypotension, tachypnea, confusion, peripheral shutdown (check capillary refill) and oliguria.
• Look for evidence of a septic focus and hyperthermia, or even hypothermia in advanced sepsis.
• Kussmaul's breathing (rhythmic, deep, gasping breaths at normal or reduced frequency) indicates severe acidosis with attempted respiratory compensation
