I am wondering...
i am learning the significance of narrowing pulse pressures, with regards to reduced cardiac output....
specifically, with chest injuries, such as a Tension Pneumo, narrowing pulse pressure is a significant finding, indicating compression of the vena cavas...
in EMT class, we spent little to no time learning about this.
we spent a lot of time learning to look for tracheal deviation. the problem is, i am also learning that this is a very late sign, and even if present, almost all the time the deviation will be below the level that you can see without x-rays, rendering it an almost useless pre-hospital sign.
so, we don't spend much time on a sign that is very useful, but spend much time learning about something we will almost never see.
am i misunderstanding something here?
