The Tandem t:slim X2 insulin pump with Control-IQ+ technology provides continuous delivery of insulin through a subcutaneously applied infusion set. The algorithm will adjust insulin delivery according to the predicted glucose when used with a compatible CGM. The Tandem t:slim Mobile App is an accessory intended for use as a connected software device that is able to reliably and securely communicate with compatible insulin pumps. Dexcom G7 and ONE+ are continuous glucose monitoring systems indicated for the management of (type 1, type 2, gestational) diabetes in people age 2 years and older where self-monitoring of blood glucose (SMBG) is indicated. Dexcom Clarity is a web-based device intended for use by both home users and healthcare professionals to assist people with diabetes in the review, analysis, and evaluation of historical CGM data to support effective diabetes management. It is intended for use as an accessory to Dexcom CGM devices with data interface capabilities. The device does not provide any medical advice and should not be used for that purpose. Home users must consult a healthcare professional before making any medical interpretation and therapy adjustments from the information in the device. Healthcare professionals should use information in the device in conjunction with other clinical information available to them.
