1. Intravenous venom (4 mg/kg) caused a non-compensated metabolic acidosis. 2. Bicarbonate concentration, base excess, standard base excess and pH all fell dramatically. 3. A respiratory impairment occurred characterized by pulmonary oedema and a fall in arterial pO2. 4. Acidosis occurred soon after venom when pO2 was still normal, indicating that changes in tissue metabolism contributed to the acidosis independently of reduced oxygen availability.

Abstract
1. Intravenous venom (4 mg/kg) caused a non-compensated metabolic acidosis. 2. Bicarbonate concentration, base excess, standard base excess and pH all fell dramatically. 3. A respiratory impairment occurred characterized by pulmonary oedema and a fall in arterial pO2. 4. Acidosis occurred soon after venom when pO2 was still normal, indicating that changes in tissue metabolism contributed to the acidosis independently of reduced oxygen availability.
