The component that best describes the effectiveness of oxygenation in a neonate is the partial pressure of oxygen levels. This measure is critical because it directly indicates the availability of oxygen in the blood, which is essential for cellular metabolism and overall physiological function. In neonates, especially those at risk for respiratory distress, monitoring the partial pressure of oxygen can provide vital information about their respiratory status and ability to oxygenate tissues adequately.

Maintaining proper oxygenation is crucial for infants, particularly premature neonates or those with underlying health issues. The partial pressure of oxygen is assessed through arterial blood gases or pulse oximetry, and it helps guide clinical interventions, such as the need for supplemental oxygen or respiratory support. Effective oxygenation is fundamental to preventing complications and ensuring proper growth and development in this vulnerable population.

Other factors like parental support or correct positioning during sleep are important for a neonate's overall health and safety, but they do not directly measure or reflect the effectiveness of oxygenation in a physiological sense. Environmental factors can also influence oxygenation, but they do not provide the specific, quantifiable data that partial pressure of oxygen does. Thus, for evaluating oxygenation effectiveness specifically, partial pressure of oxygen levels emerge as the most accurate and direct measure.
