Pulse Oximetry Plan A Primary: Physics and Equipment

This episode covers the physics behind pulse oximetry. It goes over how we can use the different absorption spectra of oxygenated and deoxygenated haemoglobin to determine their relative concentrations and therefore a saturation.
We then talk about the common issues that we encounter when using pulse oximetry in clinical practice.

A good episode to listen to before this one is Infrared Spectroscopy and Capnography. It covers the principle of infrared absorption in more detail.
