What Is Pulmonary Oximetry?

Low pulse oxes are theoretical because they couldn't just lower their oxygen until they died. So once you get below a certain threshold, I think Nick said 70%, like it's, it's almost kind of a material. If someone's pulse oxes in the 70s, it's bad. It's recognized that low ends the pulse ox. Those numbers are not, I've neither specific nor accurate. And that was completely new information to me.
