Well i can tell one on my self and that the PT may sound lost and incoherant, but may be more altogether than you think, but just have expressive aphasia. I personally was the patient, i got mad at a nurse and was yelling "who has the pink bottle, get rid of the pink bottle" what pink bottle? what do you want us to do with the pink bottle? "shove it up your @ss for all i care just get rid of it!
What was the pink bottle, Wal-mart sold a generic perfume in a pink bottle and for some reason an EMT on shift, transporting me was wearing either the "pink bottle perfume" or the origional perfume, As it was the perfume my ex girlfriend wore ,who i was on bad terms with at the time, i didnt want "her" around.
so incohereant speech had a true meaning behind it, it made sense in my head just not to the rest of the world.
Same ambulance trip as the PT. i was flown to another hospital (fixed wing) to rule out an anurysm, and when i got out of the bird and was in the ground ambulance they asked me where i was and where i was going, i replied probably close to eastern state, (eastern state is the mental hospital.) the Medic was "oh no you are going to sacred heart." Well yeah i know that! then fell back asleep,
The flight crew checked in on me 2 days later and asked me about the strange things i said, and i explained, yes i thought we landed at a diffrent airport and had we landed there, we would have been driving by the turn off to eastern state hospital estimating by how long i had been riding,
So again no matter how whacked the PT may sound, it makes sence in their head, and may remember what was said. Something i learned doing alot of mental health transports a few years ago...
so there the fireman tells a story on him self
