Subject No	20 mL		30 mL		40 mL
	PF (cycle/min)	BU (mm)	PF (cycle/min)	BU (mm)	PF (cycle/min)	BU (mm)
1	21.1	20.1	7.0	20.8	5.9	14.0
2	18.8	10.4	17.6	8.0	16.4	7.6
3	16.4	7.5	7.0	22.8	4.69	36.0
4	12.9	30.9	14.1	33.7	14.1	20.7

6	11.7	20.1	17.5	21.0	19.1	23.4

PF, primary frequency; BU, the averaged upper edge, ie, the upper boundary baseline ($\overline{B_{upper}(t)}$) for each distension.
