No delivery alarm

A no delivery alarm means that insulin is not being delivered for some reason.  Reasons could include a bent cannula, a kink or split in the tubing, or even running out of insulin.  Do not ignore this alarm.  The best course of action is to change the site.  Many times you can start by changing the site only and continue using the reservoir and tubing.  If that was not the problem and you get another alarm, pitch everything and start over with a fresh reservoir and new tubing.  If you continue to have problems after changing the site, call your pump manufacturers' customer service line and ask for their assistance.
