Hegen PCTO™ Double Electric Breast Pump is a closed circuit pump with 12 expression levels and 3 expression rhythms with a total of up to 36 personalised expression levels and suction pressure of 300 mmHg ± 20%. The 36 variations expression allows for flexibility to adapt to the speed of baby’s suckling as every child is unique and may have different suckling speeds as he/she grows. Specifications and efficiency are also benchmarked to hospital grade.
In general, Petal represents the speed of baby suckling while Level represents the intensity of baby suckling.
So for a start, we may use base on this petal:
1 petal - baby 0-3 months old
2 petals - baby 3-6 months old
3 petals - baby 6 months old n above
As for the level, it depends on how comfortable you are with the expression level. For single pumping, you can start with level 3 and for double pumping, it is recommended to start from level 5, then slowly adjust to a level that you are comfortable with, where the pump best mimics baby's latching.
