Table 1 Mean WB-CN, lactate and average COHgb

From: Effect of Hyperbaric Oxygen Therapy on whole blood cyanide concentrations in carbon monoxide intoxicated patients from fire accidents

  Mean WB-CN at arrival Mean WB-CN difference before and after HBO Mean lactate before HBO Mean lactate after HBO Average COHgb before HBO Average COHgb after HBO
Patients from fires receiving OHCob
N = 12
15.4 μmol/L 2.1 μmol/L 5 mmol/L 1.9 mmol/L 27.9% 2%
Patients from fires not receiving OHCob
N = 13
14.33 μmol/L 1.9 μmol/L 3.7 mmol/L 1.3 mmol/L 23% 1.9%
Patients from non-fires
N = 12
12.5 μmol/L 1.1 μmol/L 4.4 mmol/L 2.5 mmol/L 25.9% 2.9%
  1. Mean WB-CN, lactate and carbon monoxide concentrations before and after HBO therapy in all three groups. N = number of patients.
