A 'failing' result on the pulse oximetry test for newborns is defined as a reading of less than 90%. This threshold is critical in assessing the oxygen saturation levels in a newborn's blood, as levels below 90% indicate potential hypoxemia, which may require urgent evaluation and intervention to address possible underlying respiratory or circulatory issues.

Newborns typically should have oxygen saturation levels above 90% to ensure adequate oxygen delivery to their tissues. Values of 95% and above are generally considered normal and indicate healthy oxygenation. The range between 90% and 95% suggests the potential for concern; while it's not classified as a 'failing' result, it often warrants close monitoring or further assessment. A reading of 100% represents optimal oxygen saturation, indicating that the newborn is adequately oxygenated and does not require immediate attention.
