Someone I knew had a father who was allergic to a sure kind of wheat and it causes anaphylaxis if he does eat it. They exit tot breakfast and he asks if there may be the allergen within the meals and so they mentioned no however there was an allergen within the meals. This was in 80’s so epi pens weren’t too widespread and since he had anaphylactic shock, his throat was closing. There was a health care provider within the place that used a knife and made a gap in his throat and put a straw in it. The opening went into the trachea so he was respiratory out a gap in his neck till he acquired assist. I didn’t know you can do that so that is why I shared it.
