As far as I know, a liquid can block the windpipe, however, I've read that it can induce bronchospasm, which is a reflex that prevents water going into the lungs but it also blocks the airway. The bronchospasm normally should relax on its own, but I've read that sometimes it may last long enough to cause death. Is that true? As soon as one starts to faint, shouldn't the bronchospasm relax?
I'm asking because a few days ago I was drinking coffee in a cafe, I took a sip of it and it went down the wrong pipe. I started to cough and I managed to get the coffee out of the windpipe but afterwards I couldn't breathe. I was scared but fortunately one of the other guests slapped me on the back and I could breathe again. Nothing more came out of me so it seems that I wasn't choking on anything. Could it have been because of the bronchospasm?
