VBG vs ABG slideshow

Anne-Maree Kelly is well published in the area of many things but she has contributed much to the debate about whether ABGs are really necessary as an ED investigation in a lot of contexts.

Here is a great slide show (its self explanatory & you don't need sound amazingly) to illustrate her research and points.

ABG and VBG interchangeable?

My personal view is that of many echoed around the world. Arterial samples in ED are only really needed when you want to know what the lung is doing. If you want to know what the body is doing, then VBGs are good enough (or close enough).

For years now in my daily practice, I can only recall doing an arterial stab on patients on mechanical ventilation (invasive and non).
