Table 2 Individual nocturnal profiles of RA for six infants

Subject	Mean of RA	Max of RA	Cycle length of RA (min)
A	1.9	13.0	62
B	2.3	15.2	77
C	3.0	17.9	97
D	2.3	12.5	58
E	3.5	17.2	61
F	3.8	16.8	64
Average	2.8	15.4	70
SD	0.8	2.3	15

The RA value during the night averaged 2.8 ± 0.8 for the six subjects. The cyclic changes of RA were obtained from all subjects, and the mean cycle length of RA was 70 ± 15 min
