General Questions

I noticed my cartridge and tubing have air bubbles in them. What could be the cause?

Bubbles naturally occur in all liquids, including insulin, when they undergo a fairly rapid temperature change, i.e. warm to cool.

To help to prevent bubbles, remove insulin from the fridge at least an hour before use. If you are self-filling cartridges, make sure to fill the cartridge with room-temperature insulin and draw it from the vial slowly and steadily.

You should regularly check your cartridge and tubing for bubbles and prime out any that you find. Always remember to disconnect from your insulin pump before priming.
