	Pre-CPAP Mean ± SD	Post-CPAP Mean ± SD	p
Hyperemia area (PU)	1504 ± 979	1516 ± 680	r = 0,6
AUC (PU/s)	2.296 ± 2319	2.640 ± 2167	p = 0,01
Slope (PU/s)	0.32 ± 0.4	0.21 ± 0.23	p = 0,02
Time to latency (s)	0,99 ± 0,97	0,64 ± 0,74	p = 0,9
Time to recovery (s)	0,79 ± 0,60	0,94 ± 0,88	p = 0,37

AUC: area under the curve. PU: perfusion unit. s: seconds.
