Many pump rental stations will have a vacuum tester and can test your pump to see if the
appropriate vacuum levels are being reached.
It is used to monitor the cup's
vacuum levels.
In addition, the parameters for the test, such as
the vacuum level and the testing time may vary based on the types of requirements and methods for packaging.
Notice how with
the vacuum level turned up to 10, the suction strength is much less — 215 mmHg — while double pumping.
If pumping is painful, turn down
the vacuum level.
It offers a full set of features like 2 - Phase Expression Technology, 9 fully adjustable
vacuum levels and illuminated display that shows pumping time, battery status and vacuum level.
When you start to feel discomfort as you increase
the vacuum level is very individual and some women can tolerate a higher suction strength than others.
When you pump, you will set
the vacuum level (suction strength) on your pump to the highest level you can without feeling any discomfort.
Do not turn
the vacuum level up on the pump higher than your normal comfort level as that can actually hinder milk flow.
