ABG analysis is typically used to confirm saturation at what level?

Explanation:
ABG analysis is used to verify arterial oxygenation when saturation is already in the low range. Pulse oximetry can be unreliable as saturations fall, so an ABG provides an accurate SaO2 and PaO2 to guide treatment. This is most relevant when saturation is around 80% or less, where precise values are critical for decisions about increasing FiO2, evaluating ventilation, and assessing the severity of hypoxemia.
