Which statement describes oxygenation in neonatal ventilation?

Which statement describes oxygenation in neonatal ventilation?

• A. The removal of CO2
• B. The partial pressure of oxygen in arterial blood reflects the efficiency of oxygen exchange
• C. The maintenance of airways
• D. The removal of wastes

Answer: (B)

Oxygenation reflects how effectively oxygen moves from the lungs into the arterial blood. This is best represented by the arterial partial pressure of oxygen (PaO2): when gas exchange is efficient, PaO2 is adequate and indicates good oxygen transfer into the blood. If PaO2 is low, oxygenation is insufficient, due to issues like immature lungs, surfactant deficiency, or ventilation–perfusion problems. The other concepts describe different processes: removing CO2 relates to ventilation, maintaining airways is airway management, and removing wastes isn’t directly about oxygen transfer.
