Home O₂ therapy can be justified in patients with PaO₂ values greater than 55 mm Hg in which of the following conditions?

2) Erythrocythemia (hematocrit >56%)
3) Congestive heart failure
4) Peripheral vascular disease

Question

Quizplus · Accepted Answer

Home oxygen therapy is indicated for patients with chronic respiratory or cardiac conditions that lead to hypoxemia. It is justified in patients with partial pressure of arterial oxygen (PaO2) values greater than 55 mm Hg if they have conditions such as cor pulmonale, erythrocythemia (hematocrit >56%), or congestive heart failure, as these conditions can be exacerbated by or contribute to hypoxemia. Peripheral vascular disease is not directly related to the need for oxygen therapy based on PaO2 values.
