^ In the states, most of the meters use mg/dl, where readings below 70 are considered hypoglycemia and over 150 (generally) constitutes hyperglycemia. IMHO, pumps are great, intensive injection therapy not so much...does your aunt have T1 or T2? Ketone presence is pretty much going to be a given unless you catch it really early, in and of itself is not a major issue (insulin and a saline IV takes care of it within a day or so). However, the presence of ketones does basically mean you're developing diabetic ketoacidosis, which is fatal if untreated, so an ER visit is definitely in order.
