Plan ahead. Things can and do go wrong with an Insulin pump sometimes, so plan ahead for these. Infusion sites can fail if the catheter becomes kinked, or the tip comes out. Keep an extra infusion set with you at all times. Occasionally, the electronics of the pump fail, so keep a written copy of your pump settings with you. For the most part, pumping is very safe, but be prepared for emergencies!
Insulin pump issues. Insulin pumps do have alarms that signal when the tubing is blocked or the Insulin is running low or the battery is dying. Unfortunately, they do not warn you when the catheter has come out of the skin, which very occasionally occurs. Infection of the infusion site occasional occurs. pump failure occ occurs. Rotate infusion sites.
