Table 1 Values of arterial gas and physiological parameters at baseline, at end of HI insult, and at 60 min, 180 min, and 360 min after insult.

From: Cerebral blood volume increment after resuscitation measured by near-infrared time-resolved spectroscopy can estimate degree of hypoxic–ischemic insult in newborn piglets
