Please bear with me when I repeat what others may have already mentioned but this is how I work though scenarios and will hopefully make it easier to see where I went wrong if I end up on the wrong track or missing something important. Based on the tachycardia and low diastolic pressure I too am leaning towards a bleed, whether it was caused by the colonoscopy or missed becasue it was occuring somewhere outside of the colon is not my main concern at the moment. I would like to know if there has been any improvement to his respiratory rate since he's been on the 15L or do I have to get ready to bag him? I'm not worried about his cough right now but I'm not ready to write of the paleness as dehydration just yet (although he is undoubtably dehydrated). I'm also curious as to why he hasn't been eating, drinking, or taking his meds since the colonoscopy-- I've had a few of those myself and normally the first thing I do when I wake up is get something to eat and have a nice drink of water or ginger ale. Was he not hungry/thirsty, at which point there is probably more than a bleed going on (inflammation in the small bowel comes to mind or he could have picked up a virus somewhere) or did he simply get confused and not realize he was allowed to go back to eating, drinking, and taking his meds following the procedure? As a basic I wouldn't be able to do much more than give him oxygen and transport but if I were a medic I'd like to get a line in him and given his cardiac history would put him on a monitor as well just as much to avoid any surprises as to keep an eye on whats going on in there. I'm not familar enough with ALS protocols to say definitivly that I would give him anything more than saline because not only do I not know exactly which medications I would have at my disposal I have no idea how they work or what the possible side effects are and am not comfortable giving someone something if I don't know exactly what it should (and shouldn't) do.
