This is just a suggestion, Is it possible she may have aspirated herself? If so the vet may prescribe antibiotics to prevent aspiration pneumonia.
My friend aspirated her pig I remember at the time the vet didn't prescribe any antibiotics and the guinea pig developed pneumonia. It was a long battle to get her over the pneumonia but the guinea pig did recover.
You can only do your best - , The important thing is to get her to the vets as quickly as possible which is what you are doing. Hopefully it is just a bit of food stuck that will have dislodged itself by the time you reach the vets.....the point above about possible aspiration are also very relevant...keeping fingers and paws crossed for you.
Fingers firmly crossed! You are doing the right thing in taking her to the vets asap. It sounds like things have gone very much down the wrong way or there is a blockage, which only a vet can see and hopefully do something about. I am ever so sorry for your nightmare.
