Which of the following would indicate a need for O₂ therapy for a newborn infant? I.SaO₂less than 88% II.capillary PO₂less than 40 mm Hg III.PaO₂less than 60 mm Hg

Quizplus · Accepted Answer

A SaO2 less than 88% and a capillary PO2 less than 40 mm Hg suggest a need for oxygen therapy in a newborn infant. A PaO2 less than 60 mm Hg would also indicate a need for oxygen therapy, but it is not the best answer because it is redundant with the other two options. Therefore, the best choice is B, which includes the two most relevant indicators for oxygen therapy.
