Figure 3.

Oxygen saturation (SpO₂) according to AHA guidelines should be targeted at 70–75% at 3 min and 80–85 at 5 min. Heart rate (HR) should be targeted at >100 bpm in the first 2–3 min after birth. Red and blue rectangles define the normality ranges for SPO₂ and HR, respectively, at different postnatal timings after birth (Graph modified from reference [28]). Red and blue rectangles define the upper and lower of normality ranges for SPO₂ and HR, respectively, minute-by-minute in the first 10 min of life.
