When it comes to changing sites, the Pod is no different than a regular
infusion set. If you have bolused recently or are running a fairly high
basal rate, when you remove the infusion site the opportunity for fluid to
leak from the wound is high. Think for a moment about the size of a 5 unit
droplet of insulin at the tip of an infusion set. If you can't visualize
it, try bolusing that amount before inserting and look at the droplet.
That amount of insulin can easily leak out of a wound and upset blood
sugar levels for several hours. It is SOP to leave an infusion site in
place for at least 2 hours after you've stopped infusing insulin before
youo remove the site.
