Understanding Pulse Oximetry: Principles, Mechanics, and Errors

I'm back today with another "MiniPod" where we discuss the principles of Pulse Oximetry and sources of error. This is a core clinical measurement topic and an examiner favourite with a low SAQ pass rate. I first start off with the basic principles of how the device works (00:40) and then talk about the common sources of error (08:19). Then I look at the past SAQ's, lucky there is only two options on what can be asked (12:52). Finally, we look at the past viva opening stems and discuss some weird questions that can be asked (16:49). I hope you enjoy the Podcast and if you have any questions please email me! As always thank you for listening!
