I guess more of what I was getting at was that do you know what to feel for when palpating a liver? I would expect you to know which quadrant the patient is having pain in and what you've done for that pain...It's unrealistic in my opinion to ask an EMT or Medic to know how to palpate the abdomen to a doctors standards. It will also have minimal impact on your treatment in the field.
With regards to the AAA, a light touch midline will reveal a pulsating mass or not, no need to do much more palpation that that. On the super skinny elderly, you should be able to palpate a pulse from the AAA and should correlate with their Apical pulse.
I apologize if I seemed harsh with my comments, I'm just against causing more pain unless it's necessary, and in most cases in the field it won't change your management or transport criteria... Maybe one of the more experienced medics around here can help. I am absolutely for a thorough exam and learning as much as possible.
What more is the hospital looking for other than LRQ pain, patient hx of general abd pain, n/v, possible appy... all of that can be done without causing further distress to the patient in the ambulance and increase their anxiety/pain level before the doc gets to see them.
Edit to fix my tired spelling/grammar...
