9. Expressing your breast milk
To avoid health risks and reduce the risk of injury:
16
• Milk expression should not be uncomfortable. Very powerful vacuum, misaligned nipple
or incorrect breast shield size can cause trauma to the nipple/breast and decrease milk
output. Adjust the breast shield size (see chapter 15) and vacuum as needed.
• Stop using the breast pump if discomfort persists or in the event of negligible milk
output. Please contact your healthcare professional or breastfeeding specialist.
• If you experience pain during pumping, break the seal between the breast and the
breast shield with your finger and remove the breast pump from your breast.
• Stimulation phase is a fast pumping mode to stimulate milk flow.
• Expression phase is a slower pumping mode for gentle and efficient milk removal.
• Maximum Comfort Vacuum (MCV) is the highest vacuum setting where pumping still
feels comfortable. This is different for every mother and will result in the most efficient
milk expression.
• When in Expression phase, increase the vacuum with the + button until pumping feels
slightly uncomfortable (not painful). Then decrease the vacuum with one press of the –
button. This is your MCV level.
• It is important to identify the MCV during the first pumping session as this vacuum
level will be remembered by the breast pump. The breast pump will adjust the vacuum
automatically to the MCV level during the next session. While the breast pump adjusts to
the MCV level, the + button will be flashing.
• Consider reassessing your MCV each week to ensure you are pumping at your optimal
vacuum level.
