EMCrit Lecture – Dominating the Vent: Part II

When I was a resident, every vent lecture either put me to sleep or left me dazed and bewildered. I gave a lecture of that ilk when I started working after fellowship. I had become part of the problem. I decided there must be a way to make vent management more understandable and if not interesting, at least bearable.

This lecture was up on the soon to be defunct EMCrit Lecture site. It offers a path to managing any patient on the ventilator in the ED. I have tried to simplify as much as possible while still maintaining an evidence-based approach.

This is Part II, it deals with the obstructive strategy. Last week, we spoke about the strategy for patients with  lung injury.

Your goal with these patients is to let them have adequate time to breathe out.

There are only 4 things you need to remember for an obstructive patient

Vt (Tidal Volume) = 8 ml/kg, don’t mess with it

Flow Rate = shorter insp times, 80-100 lpm

Resp Rate = Lung protection, start at 10 work your way down if necessary

FiO2/PEEP = Oxygenation, should need much O2 (40%)m I recommend PEEP of 0, but certainly keep it less than 5
