Breast Pump Glossary and Breastfeeding Terms

A feature on some breast pumps by Medela (Symphony, Pump In Style Advanced, not Original, and the Swing), that starts the cycling fast with less suction then after two minutes switches to slower cycling with more vacuum strength to imitate the sucking patterns of infants. A special let-down button can be pressed once to go instantly to the second mode. The manual breast pump Harmony is also said to have 2-phase. The first phase is initiated by squeezing the short part of the handle, with the longer, stronger strokes of the second phase coming from switching the hand around to squeeze the long part of the handle. 분당스웨디시

For mothers concerned about low milk supply a baby scale is a tool to verify baby’s weight gain and also the amount of breast milk received in any given nursing. By weighing the baby before and after nursing and doing a little subtraction, one can determine the number of ounces the baby nursed from the breast. Since a nursing baby is usually more efficient than any breast pump, this method is preferred to breast pumping for determining how much milk the baby may be getting. For these purposes a baby scale accurate to 15 grams or less may be rented from many breast pump rental stations.

battery pack, batteries

In a breast pump, batteries give cordless convenience but vacuum strength and cycles per minute may be less than the user will find when using the AC adapter. Also pump cycling may slow as the batteries wear down. Slower cycles may cause some discomfort because the vacuum will be held longer on the breast. If this happens, reduce the vacuum and replace the batteries with fresh ones as soon as possible.

breast pump

A device that expresses milk from the breast. A misconception is that the breast pump suctions milk out of the breast. A breast pump’s job is to trigger the milk-ejection response or let-down. Most pumps achieve this goal by using suction to pull the nipple into the tunnel of the breast shield or flange then release, which counts as one cycle. Thirty to sixty cycles per minute can be expected with better quality electric breast pumps. It is important to note that in most cases the breast pump is not as efficient at removing milk from the breast as the nursing baby. Many mothers find their milk supply dwindling when they substitute too many pumpings for actual nursing sessions with their baby.
