Hi, we are in the midst of implementing air breaks at our center which obvioulsy involves updating and revising our protocols. My question is it up to our medical director to subjectively choose protocols based on rather loose and somewhat vague suggestions based on available references? In other words their does not seem to be any reference material that is universally accepted that states concretely what treatment protocols should be. 2.0 vs 2.4 ATA, air breaks for 2.0 vs 2.4? air breaks for co2 retainers...etc. 2.0 for osteoradio. vs 2.4.? Seems to me trial and error plays a significant part in treatment protocols- if we arent seeing any improvement at 2.0 then increase treatment to 2.4......Thank you to those that can reply..
