Vacuum Intensity
The vacuum level on your breast pump refers to the suction strength, or how
strongly the pump will ‘suck’. This is measured in mmHg. When you are using
your Spectra S1, you will usually find that expressing is most effective on the
highest vacuum level that you are comfortable with. However, it’s important
not to set vacuum level so high that it makes you uncomfortable, as the
resulting pain will hinder your milk flow.
• Adjust the vacuum intensity by pressing the and buttons
between levels 1 and 12. Start off with the vacuum on low, and then
gradually increase the vacuum setting to your comfort level.
• To achieve best results, we recommend trying to pump with the
vacuum set to your maximum comfort level. You may try switching
between your maximum comfort level and a lower intensity to
stimulate more milk let down as well. Be sure not to pump above your
comfort level as that may hinder milk flow or cause injury.
• Since the Spectra S1 automatically starts back up where you left off,
we recommend slowly decreasing vacuum intensity at the end of
your pumping session (this eliminates any ‘surprises’ when you go to
pump the next time).
