We take pulse oximeters for granted working in the NHS - we use them everyday, they're cheap and readily available to help measure our oxygen levels - but how do they actually work?

This is a different style of vid from you Ollie, be keen for you to do more in this series. Cheers

Great succinct explanation! I think it's worth adding that pulse oximetry, by the very mechanism you described, has proven less effective in those with darker skin, particularly at lower saturations. Lots of papers discussing this but yet to be suitably addressed AFAIK. I think it's definitely something to bear in mind as a HCP or a patient yourself. For the most part it's a very useful adhoc tool though.

Very true and something I am indeed aware of - definitely good to raise though, will add a note to the description later

Only 945 views??? I thought your videos would be in the 6 figures (you produce some high quality videos!!). As a medical student myself I find your videos really useful to watch, can’t wait to see what’s next :))

Thanks Ollie. Well explained

Yes, thanks for the content, very informative. I just wanted to add that when these were invented they were a virtual godsend. The alternative is a traditional arterial blood gas which involved a very large needle stuck deeply in the patients wrist or groin to access an artery. The procedure was painful under the best of circumstances and extremely painful for children, the elderly, and those with diminished capacity because struggle against the pain turned pain into agony.

You're so right, I hate doing ABGs still. In emergencies there's often no choice but I certainly don't go out of my way to do them

Low saturation is not a disease but an index, you can have good saturation and heartbeat and die of pain in COPD pulmonary emphysema and pleural fibrosis plus ankylosing spondylitis
