I really cannot believe some of the responses I am reading. If you use proper lifting mechanics, you will not injure your back. C'mon, we are talking about a 120ish pound man. Every one of us should be able to carry him unassisted, much less with 2 people. Many State's, Texas for instance, requires an ability to lift a particular weight. Can't do it? Then you are not fit to perform your job description. Simple as that. An excuse is all it is. All of this "you are just like the other 10 people we have seen" and the "if they can, they will walk" is B.S.
STOP BEING LAZY AND DO YOUR JOB!
Put a little thought and care into your patients, it won't kill you, you will still get a paycheck, and I don't know, maybe it will make you feel good about doing the right thing instead of being self-centered. If its a problem, then maybe you need a vacation...............
It is so easy to say that he should have refused to walk. The general impression that most get is that EMS will do the right thing for their patient. The pt. and / or family called for assistance, nothing more should be required. the rest is in YOUR hands.
