Summary of parameters used by the NeoNNS application.

UnitsDescriptionReference

NNS threshold(cm·H2O)NNS peaks with amplitude greater than this value used as feature extraction[10]
Half-height cycle width(ms)NNS cycle width at half-height less than this criterion used as feature extraction[38]
Minutes/seconds(min/s)The time epoch of the most active NNS period[10]
DiscrimStepSize(samples)Sliding window size to localize the most active period of sucking
BurstCriterion(ms)Two or more NNS events occurring within this value[10]
Number of compareNumber of NNS bursts[39]
Number of cyclesNumber of successive NNS cycles[39]
