Total response duration and characteristics. A: infusion volume (black bars: control; gray bars: HIE). *P < 0.05 for volumetric effect compared with 0.5 ml; †P < 0.05 for volumetric effect compared with 0.3- and 0.5-ml infusions; volumetric PRS recruitment to aerodigestive quiescence. Note HIE patients have a significant volumetric response for 0.1-ml infusions compared with 0.3- and 0.5-ml infusions. Control infants have a significant volumetric response between 0.1-ml infusions compared with 0.5-ml infusions. B: durations of respiratory change (open squares: control; open triangles: HIE). *P < 0.0001, respiratory change duration is highly correlated with terminal swallow latency in HIE infants.
