So at our last webinar (still to be edited due to an unfortunate trolling event), we briefly touched on modes of ventilation but really didn’t delve into it very deeply, so, being fortunate enough to know some really smart people, I figured I might gather up these two for a quick chat. They are both known for no-nonsense, out-of-the-box thinking, paired with solid physiological thinking, which in my mind is the only way to approach complex problems and system failure. Plus, with Rory (@EMnerd) and his powerful nihilistic approach, there would be no chance for a whimsical approach, it would have to have a base in physiology, evidence (bedside or literature) or both!
So just as a little brain teaser, I would like anyone reading to think about how many severe respiratory failure syndromes they are aware of that attack the lungs in a predictable volumetric fashion, where one can say, for instance, that consistently, X% of the parenchyma is affected. Kinda hard, huh? Yet, if asked how best to ventilate these patients, most of us who feel we have a good grasp of severe respiratory failure would answer without thinking twice: “lung protective ventilation: good peep and 4-6 ml/kg.” In a lear, confident tone, most likely as well.
Now I would say that only the first part is correct: lung protective ventilation. As to the second part, it would, to me, only hold true with uniform pathology and uniform patients. But I’ll let Rory rant about that himself, it’s far more entertaining!
So here is our chat.
Hope everyone gets something out of it!
