[QUOTE="jopar, post: 231414, member: 11712"] Air bubbles can appear at any time, due to temperature changes, Insulin is a liquid so as it's temperature fluctuates it will release and adsorb the air molecules. Tip, is to wear your pump with the luner lock facing downwards, if air is released from the insulin, it then collects at the other end of the cartridge away from the tubing out of harms way. If you've got frothing in your tubing then this means that you have a lose luner connection, if the lock isn't tight it will allow air to seep back in frothing the insulin, Tip, when you check for air bubbles which you should do regularly during the day give the luner connector a twist to ensure that it's tight.. Priming out bubbles when filling up a cartridge, if you are getting frothing at this stage it means that you are pulling the plunger back to quickly, let the air you've pushing to the vial slowly push the insulin into the cartridge then slowly without wobbling the plunger from side to side pull plunger back the rest of the way.. Tip when filling from the vial, inject the air with the vial stood on the table top, the handle to vial gently when you rotating it into the upward position to fill the cartridge, as quick fast movements will froth up the insulin and create more bubbles which are finer and very much harder to knock out when you got them in your cartridge [/QUOTE]
