Normal PaO2 decreases with age . 5. The body does not store oxygen . Therapy & Diagnosis: 1. Supplemental O2 is an FIO2 > 21% and is a drug. 2. A reduced PaO2 is a non-specific finding. 3. A normal PaO2 and alveolar-arterial PO2 difference (A-a gradient) do NOT rule out pulmonary embolism. 4. High FIO2 doesn’t affect COPD hypoxic drive . 5.

WebBackground: Arterial blood gas (ABG) values and the alveolar-arterial oxygen (A-a) gradient are sensitive indicators of pulmonary pathology. Alone, they are not diagnostic of pulmonary embolism (PE), but they may be useful in excluding the diagnosis of PE if their values fall within the normal range. WebThe ABG levels can be normal or exaggerated. The alveolar‐arterial (A‐a) gradient is almost always elevated. Usually there is an increase in this gradient of more than 30. The normal PaCO 2 is 35–45 mmHg, and less than 35 mmHg represents excessive carbon dioxide elimination or hypoventilation. For every 10‐mmHg increase in PaCO 2 over ... WebA-a O₂ Gradient.
