Changes in PaO₂ and CaO₂ after Initiation of Home Oxygen Therapy.

After starting home oxygen therapy, a significant increase in arterial partial pressure of oxygen (PaO₂) was observed (A, B), while arterial oxygen content (CaO₂) remained virtually unchanged (C, D). This finding shows that, despite the improvement in PaO₂, total oxygen transport capacity does not change substantially.
