What do all of those dials on the ventilator do? Well, Scott Weingart has a great two part series on Dominating the Ventilator that explains them, and how to use them to help your patient. I have posted his video podcasts below, along with some of his notes, but you can find the links to his original postings listed below as well.
Part I, deals with the lung injury strategy. In part 2 below, he talks about the strategy for patients with obstructive lung disease.
There are only 4 things you need to remember for a lung injury patient:
Vt (Tidal Volume) = Lung Protection
Flow Rate = Patient Comfort
Resp Rate = Ventilation
FiO2/PEEP = Oxygenation
This is Part II, it deals with the obstructive strategy.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
