Can someone give a good explanation of DKA versus just having ketones. We had a pump problem(I think he didn't reconnect) and in the morning he had ketones and vomiting. We gave shots and kept checking and the BG's came down and the ketones came down within 4 hours I think. Not sure if that is DKA or just ketones??? Our ketones that time were 1.6 I believe on the meter.
