In Part 2 of our series on airways and ventilation, Liam and Fiona take us through the principles of NIV. If you've ever been baffled by PEEP, CPAP and BiPAP, this is the episode for you!

This episode is also crucial to listen to before our next episode, where we cover a lot of similar principles in the context of invasive ventilation.
