Nasty old things - good that polio is a thing of the past. I remember colleagues telling me it was all hands on deck when the power went out, and you had to crank them by hand. Some patients could sit out and breath by moving their torsos up and down, but it was tiring. There was another egg shaped one you could sit up in.
