Venous Blood Gas, You Rock!

We had a long journey to get here! I can’t tell how many times that I had argument with consultants regarding COPD or DKA patient that they ask for ABG and we had VBG! My old Post was focused mostly on DKA patient but Thanks to Throax that published a study among COPD patients.

Using venous blood gas analysis in the assessment of COPD exacerbation: a prospective cohort study: UK based study, 234 patients with COPD exacerbation. There is a great agreement between arterial and venous measures of pH and HCO3. The mean difference amazingly looks good in their analysis.
