Interpolating arterial blood gas results is a tricky business and it confuses many nurses, myself included.
In an attempt to try to simplify the whole process I have produced a short video to help you get your head around it all.
Remember, I have greatly simplified the whole thing in an attempt to at least get a footing in the process. If the video does clarify things a little, you might like to follow up with some further reading on the topic.
Please let me know if this presentation was of any use to you or, alternatively,Â if it confused you even further.
