Everything Blood Gases on the Internet
Below is an annotated list of my web sites, plus others that provide
useful information. I've also included a category of web sites for the
general public.
My web sites on ABGs
All You Really Need to Know to Interpret Arterial Blood
Gases
Information about my book, the #1 bestseller on Amazon.com dealing
with arterial blood gases.
Differences
between PaO2, SaO2, and Oxygen Content - How Much Oxygen is in the Blood?
Many trainees caring for critically ill patients don't fully understand these important differences.
Blood Gas Quiz
A not-too-easy multiple choice quiz, with detailed answers.
Blood Gas Interpretation - What's new
Non-invasive methods of assessing blood gas information.
Diagnosing mixed acid-base disorders
A quick review of this important topic.
The Anion Gap and the Bicarbonate Gap
AG is very important in unraveling mixed acid-base disorders.
Less well understood is the bicarbonate gap.
Blood Gases on Mt. Everest
Based on 2007 expedition to the summit, published in NEJM
Interpretation of Arterial Blood Gases (Powerpoint slide presentation)
Slide presentation for physicians and medical students - with case questions.
Why is the PCO2 Equation the most important equation in all of Clinical Medicine? (Powerpoint
slide presentation)
This slide presentation explains why the PCO2 equation is the 'center of the
blood gas universe'.
You can't learn blood gas interpretation from a lecture (Powerpoint slide presentation)
A lecture can point you in the right direction and highlight what's important - but you won't
learn the art of blood gas interpretation from any talk; you must instead work on problems on your
own.
Other Web Sites on ABGs
Acid-base tutorial
Authored by Dr. Alan Grogono, former Chairman of Anesthesiology at Tulane, this web site offers a wealth of instruction. Perhaps unique
among web sites on this topic, he provides historical insight into why acid-base terminology is such a mess (see his topic "Topsy Turvy Decisions").
Anesthesiology Education website on Acid-base physiology
Includes an 11-chapter text on Acid-base physiology, plus
30 case examples that are thoroughly discussed.
Blood gas measurements
Site from the UK - emphasis on actual measurements of pH, PCO2 and PO2, as opposed to interpretation of results.
www.the-abg-site.com
ABG Site "dedicated to helping nurses and other healthcare professionals learn and interpret arterial blood gases." Contains
samples for you to interpret.
Brief Review from
British Medical Journal
In addition to information about ABG interpretation,
shows pictures of arterial sampling and the Allen's Test for arterial blood flow.
