Which of the following would indicate a need for O₂therapy for an adult or child? I.SaO₂less than 90% II.PaCO₂greater than 45 mm Hg III.PaO₂less than 60 mm Hg

Quizplus · Accepted Answer

Low PaO2 level (less than 60 mm Hg) and high PaCO2 level (greater than 45 mm Hg) indicate respiratory failure, which is a potential indication for O₂therapy. SaO2 level less than 90% also suggests respiratory distress, but it is not as specific an indicator as the PaO2 and PaCO2 levels. Therefore, only statements I and III indicate the need for O₂therapy.
