When we are trying to determine a patient’s acid-base balance, routinely arterial blood gasses are drawn. Explore the literature for information supporting the use of an arterial blood draw instead of the conventional venous draw. Original Post – First, summarize your understanding of why it makes more sense to investigate arterial blood instead of venous blood when dealing with an acid-base issue. Next, present your outside source(s) and then summarize, in your own words, the most important piece of evidence from your article. Be sure to cite your source and include a link or copy/paste a direct quotation from the most relevant portion of the source to enable your classmates to view and evaluate the information.
