Which response BD (breath duration) or PD (pause duration)

Duration of Bursts and Pauses: BD was longer for BoF1 and BoF2 than for BrF1 and BrF2, decreased late in feeding sessions when compared to BD early in feeding sessions for both br bottle-feeding. This decrease in BD late in feeding sessions was statistically significant (p = .0 BD and PD early and late in feeding sessions are depicted in Figure 1. PD was longer late in fe both feeding methods. This increase was greater during breast-feeding sessions when compa sessions. There were statistically significant differences for both the change in PD late in fee 025) and for the differences between feeding methods (p = .039), but not for the interaction factors. 21 17 Duration (sec) 15 - BrF Burst BrF Pause 13 - - Bof Burst BoF Pause $1 N Time FIGURE 1. Comparison of burst duration and pause duration at time 1 (early) and time 2 (lat bottle-feeding sessions. Sucking Rates: There were no statistically significant differences for SR between the for the time in feeding session. This finding confirmed that nutritive sucking was measured and bottle-feeding, as faster sucking rates would be expected during breast-feeding session was not present (e.g., if there was no milk flow). Breathing Rates During Bursts and Pauses: RRB was faster during breast-feeding when feeding sessions. RRB increased slightly from BrF1 to BrF2; the faster breathing rate in BOF
