  • However, a decrease in pO2 as well as oxygen saturation has been noted. 7-9 Patients with G6PD deficiency appear to be more susceptible to methemoglobinemia. 1


  • This is reflected in a leftward shift of the oxyhemoglobin dissociation curve. 17 Therefore, in cases of methemoglobinemia, a normal pO2 should be expected even in patients with cyanosis.

  • The addition of lactate to the epoc BGEM Test Card, which includes in vitro diagnostic tests for pH, pO2, pCO2, Na, K, iCa, Hct and Glu (plus calculated values), further expands the clinical utility of the Company's point of care blood gas and metabolite cleared for use on the epoc System in the past 12 months.


  • Exposure to room air, either through not sealing the specimen or not removing air bubbles, can moves pO2 towards the pO2 of the ambient air (150 mm Hg at sea level).
