Three Expression Programs

Low Milk Production is often the cause of insufficient stimulation. As an infant grows older, their feeding patterns and suction strength changes.  These natural changes in a baby’s feeding pattern encourage stimulation, allowing the mother to express enough milk for her baby throughout the duration of the breastfeeding period.

Mothers who use breast pumps with non-varying patterns and suction strengths may experience a decrease in their milk production rate.  This is due to the level of stimulation decreasing over long-term exposure to the same patterns and strength.

Rumble Tuff’s Serene Express Duo Electric Breast Pump has been uniquely designed to address this issue with the 3 Expression Programs. The 3 Expression Programs and 8 levels of suction strength provide mothers with varying levels of stimulation; mothers can alternate between these settings to mimic how their baby’s feeding habits change as they grow, encouraging strong and steady milk production.

We encourage mothers who use the Serene Express to alternate between the 3 Expression Programs and their suction strength to provide sufficient stimulation for their milk supply.


Three Expression Programs Design & Theory

Reflex Performance

The Reflex Expression consists of the first 15 cycles when the pump is turned on. There is no preset vacuum level for this expression phase. The vacuum level begins approximately 3kPa (22.5mmHg) higher then the Swift Expression setting and reduces by 0.25kPa (1.88mmHg) per cycle before transitioning to the Swift Expression at the 16th cycle. This pumping phase can only be reactivated by turning the pump off and turning it back on again.

Theory
This phase imitates the reflexes of a hungry baby when he first latches on and initiates stronger vacuum suction. As the baby’s mouth begins to fill with milk, he gradually reduces his suction strength.

Swift Performance

The Swift Expression consists of a fast and shallow pattern with reduced suction. Mothers can choose between 8 levels of vacuum suction strength. There is no preset time limit for this phase, and mothers can toggle to the final phase at any time by pressing the Expression Button.

Theory
This phase imitates the fast and shallow nursing pattern of an infant or baby with similar nursing habits. This helps the mother achieve letdown. The Swift Expression allows the mother to adjust the pump’s suction patterns at will, achieving the milk production stimulation she would naturally receive from breastfeeding her baby. Mothers can choose to remain at this expression phase if her baby is still small or she can switch to the final pattern as her baby’s nursing patterns change.

Natural Performance

The Natural Expression consists of long and deep suction cycles with no preset time limit. Mothers can choose between 8 levels of vacuum suction strength and can toggle back to the Swift Expression pattern by pressing the Expression Button.

Theory
This phase mimics how most babies naturally obtain milk from their mother’s breast through long and deep suction patterns. 8 levels of vacuum strength allow a mother to choose the suction strength which most closely mimics her baby’s suckling strength.
