Fig 3. Courses of ΔCBV (A, E), cTOI (B, F), SpO₂ (C, G) and HR (D, H) within the first 15 minutes after birth (A, B, C, D) and during the first 60 seconds after initiation of respiratory support (E, F, G, H) in SLI (circles) and control group (diamonds); values are mean (95% CI); *p < 0.05; significances are calculated between SLI and control group; ΔCBV are related to a reference value at 15 min (A) and 60 seconds (E).

CBV, cerebral blood volume; cTOI, cerebral tissue oxygenation index; HR, heart rate; SpO ₂, peripheral arterial oxygen saturation.
