INS and Hyperglycemia: According to studies, hyperglycemia can occur for different reasons, such as: blocking the insulin infusion due to cannula dislodgement [13, 21, 25, 30, 31, 78, 92, 93]; incorrect setting of basal rates or non-administration of bolus insulin [30]; the amount of insulin in the reservoir finishing [30]; battery running out [30]; and system occlusion [15, 33, 78, 83, 93, 94].
