hypoxemia การใช้

• Arterial blood gases may reveal hypoxemia when tested in a lab.
• The A a gradient is useful in determining the source of hypoxemia.
• Polycythemia can occur secondary to increased erythropoietin production caused by the chronic hypoxemia.
• Severe lung injury and hypoxemia result in high mortality.
• Pulse oximetry can provide an early warning of hypoxemia.
• In an acute context, hypoxemia can cause symptoms such as those in respiratory distress.
• Chronic hypoxemia may be compensated or uncompensated.
• Airflow limitation is uncommon; gas exchange is usually abnormal and mild hypoxemia is common.
• If the level is below 90 percent, it is considered low resulting in hypoxemia.
• Hypoxemia during flight presents independent risks.
• The most common causes of hypoxemia are ventilation-perfusion mismatch, hypoventilation, and shunts.
• Arterial hypoxemia in these patients has been attributed to ventilation-perfusion inequality and intrapulmonary shunting.
• A prescription renewal for home oxygen following hospitalization requires an assessment of the patient for ongoing hypoxemia.
• Acute cor pulmonale is manifested by respiratory distress, hypoxemia, hypotension and elevated central venous pressure.
• Although severe hypoxemia is generally included, the appropriate threshold defining abnormal Pa has never been systematically studied.
• When midazolam is administered in combination with fentanyl, the incidence of hypoxemia or apnea becomes more likely.
• The oxygen content of blood is thus sometimes viewed as a measure of tissue delivery rather than hypoxemia.
• Oxygen supplementation is common in the treatment of hypoxemia, an abnormally low level of oxygen in the blood.
• Evidence against cytotoxic edema includes the high levels of hypoxemia ( low bloodstream oxygen ) needed to cause it.
• Hypoxemia is present in nearly all patients with FES, often to a PaO2 of well below 60 mmHg.
