This episode we're going to cover how we measure blood pressure in clinical practice.
We'll cover the automated and manual BP cuffs, the Finapres system and the arterial line.
We'll also go over the physics behind the Korotkoff sounds.

This week we are covering the beast of a topic that is MRI.
We'll cover the basics behind nuclear magnetism, alignment and stimulation.
We will also discuss relaxation times and how different weightings can give us different images.
Finally we will talk about the practical implication of having a patient in the MRI scanner whilst anaesthetised.

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.

This episode covers the physics behind the pH and Severinghaus electrodes used to measure pH and the partial pressure of carbon dioxide in blood gas machines.
It also covers how we get our bicarbonate and base excess values on blood gas results despite not measuring it directly.

This episode covers the different methods of measuring oxygen concentration in anaesthetics. We'll cover how oxygen's oxidative properties allow it to be used in electrochemical sensors such as the Fuel Cell and the Clark Polarographic Electrode.
We will also cover how its paramagnetic properties allow it to be measured with the application of a magnetic filed, such as in the null-deflection and pulsed-field paramagnetic analysers.
