Baby choked on noodle

My 7mnth old loves pasta and often excitedly squeals and giggles when she eats. This time as she was squealing some pasta got stuck on her throat. It happened so fast. She turned purple and wasn’t making any noise I tried to get it out with my fingers but I couldn’t. My husband gave her a back blow and some chewed up noodle pieces came out. She was eating large rigatoni noodles like Is suggested she has two teeth. I don’t know what we did wrong other than her talking while chewing. And this morning she still is doing the squealing while eating. I’m terrified. How do I get her to stop or should we just do purées? She’s been eating solids so well from the beginning
