Before I release my vodcast about some of the non-invasive experiments I've been working on, I wanted to do a back-to-basics podcast about positive pressure ventilation. In this quick vodcast we will cover why we give extra pressure behind our oxygen, a little about V/Q mismatch, and how titrating different pressures will yield different results!    I'll attach some of the pictures from the Vodcast so that you can see them in still motion without having to pause the video.
