Although maintaining adequate oxygenation is a fundamental aspect of newborn care,
clinicians are only beginning to appreciate how even subtle alterations in oxygen levels can
affect both short-term and long-term outcomes. Before the implementation of noninvasive
technologies, oxygen assessment was limited to intermittent arterial sampling, which only
gave a glimpse of the true instability of oxygen levels that can occur during early postnatal
life. Current continuous recordings of oxygen saturation reveal a much higher frequency of …
