Well, I'm an anaesthetist, and have heard this argument.

I personally did a heimlich maneuvere on a hospital inpatient who was blue and choking on a big bit of bread, and the bread came out and he turned pink again.

So from my samples size of N=1, it works 100% of the time. I would like to know the high quality randomized controlled trials which show that it doesn't?

Just like Lisa's rock. Nothing works 100% of the time, and obviously they do not use "high quality randomized controlled trials" since killing people is not ethical. Current recommendations are to begin with back blows.
