Скажите пожалуйста, откуда брали кровь для анализа КЩС? Меня смущает низкий показатель РО2

standard arterial and venous blood gases to compare the partial pressure of oxygen in venous blood (PvO2) with that of oxygen in arterial blood (PaO2). PaO2 is usually normal or low-normal in cases of CO poisoning but PvO2 is abnormally high, indicating substantial impairment of oxygen delivery from arterial blood plasma into tissue. Venous blood for the PvO2 analysis should be drawn at the elbow without a tourniquet. The optimum PvO2 level in healthy non-smoking adults is about 25mm Hg, while levels in CO poisoning (and CFS/FMS/MCS) patients are commonly in the range of 30 to 50. The optimum atereo-venous gap is 70 to 60mmHg: a smaller P(a-v)O2 gap is clear evidence that oxygen delivery to tissues and/or its uptake is impaired.

Т.е. РО2 артериальной крови должен быть нормальным или немного пониженным, а венозной - аномально высоким. А у пациента РО2 - очень низкий...
