A false peak in the milk flow rate of a mother measured by the Showmilk that was due to pooling during breast expression. Three milk ejections (increases in milk flow rate ↓) can be observed. Milk ejections have a distinct shape with milk flow rate increasing steeply until the peak and then decreasing at a slower rate. However, in this example, after the first milk ejection, milk was pooled in the breast shield and released suddenly at the second milk ejection creating a narrow false peak (Δ) which could be mistaken for separate milk ejection. The cumulative weight of the expressed milk of the left breast is represented grey. The weight data is derived to obtain a milk flow rate value in g/s and is represented in orange.
