Correction: Arterial PCO2 = PvCO2 - 8 (in the video I mentioned it's + 8)

Thank you for the fantastic video - Why are VBGs not good in patients who are hypotensive? - Is it because the venous blood has more contact with the tissues of the body and thus has an increased amount of CO2 dissolved in it when compared to arterial blood? And if so, is this difference significant enough to contraindicate its use?

Nice presentation and one comment. Arterial PCO2 = venous PCO2-5 and not +5

If an individual is a smoker, how long after the last cigarette would the oximeter reading be closer to accurate? Thanks
