I had a call like that once. Difficulty breathing, but the patient exceeded the weight of our gurney (400 lbs). Fortunately, the city had a heavy lift ambulance and super-size gurney. Of course you can't just leave the patient there with some oxygen and a pat on the back, so we waited with her for the other ambulance. The whole time, this bedridden woman (her knees couldn't support her weight), was consuming a plate full (stacked like a pyramid) of sweet rolls. This takes a little work considering we had her on oxygen and she was slightly short of breath. Not something I will ever forget especially when I am considering that extra treat.....
