I can't dispute it, because if you notice I said that yes, it's an assessment of the patient. But as far as the basic partner is concerned, you'll be using a 20 unless told otherwise. They are all in the box in front of me, so if he sets out a 20g, and I decide I want to use an 18, I just have to move the two inches over and grab it. But a 20g is assumed, because it's the most commonly used.
What I take exception to is you...
...and you, making these judgment calls on EVERYTHING people say here that doesn't conform to your own theology of EMS. I get it, every patient is different, every judgment should be made independently without bias or preference blah blah blah... But you know as well as I do that certain routines happen, and sometimes happen for good reason and not just laziness.
We prefer the 20g, the hospitals prefer the 20g, but we use something else when it warrants. Why exactly is that wrong with you guys, as it seems to conform to what you guys are saying in all but the philosophical zen aspect of your statements.
