A friend's coworker had their pump lock on, and inject the entire reservoir of insulin into them. They were discovered in their home by the police after family members lost contact. No idea if it was an Omnipod, but I would hope that all insulin pumps have a separate watchdog circuit to prevent this.
My wife is T1 diabetic and has the Tslim pump. When there is an occlusion at the infusion site insulin stops being delivered and blood glucose goes high.
It never occurred to me that a pump might fail in a way to give her too much insulin...
My daughter is T1 as well. This bothers me every time I think about it. You are probably already aware but if your wife is using the dexcom there’s an app called follow that she can add you to to get alerts if things go awry (highs or lows).
She probably won’t want to use it but if she worries about that at all it might provide some peace of mind.
