hypoxemia

/hy·pox·emia/ (hi″pok-sēm´e-ah) deficient oxygenation of the blood.

hy·pox·e·mi·a

(hī′pŏk-sē′mē-ə)
n.
Insufficient oxygenation of arterial blood.

hy′pox·e′mic adj.

Hypoxemia

An abnormally low amount of oxygen in the blood, the major consequence of respiratory failure, when the lungs no longer are able to perform their chief function of gas exchange.

hypoxemia

[hī′poksē′mē·ə]
Etymology: Gk, hypo + oxys, sharp, genein, to produce, haima, blood
an abnormal deficiency in the concentration of oxygen in arterial blood. Symptoms of acute hypoxemia are cyanosis, restlessness, stupor, coma, Cheyne-Stokes respiration, apnea, increased blood pressure, tachycardia, and an initial increase in cardiac output that later falls, producing hypotension and ventricular fibrillation or asystole. Chronic hypoxemia stimulates red blood cell production by the bone marrow, leading to secondary polycythemia. Hypoxemia caused by decreased alveolar oxygen tension or underventilation improves with oxygen therapy. Hypoxemia resulting from shunting of blood from the right side of the heart to the left side without exchange of gases in the lungs is treated with bronchial hygiene and positive end-expiratory pressure. Also spelled hypoxaemia. Compare hypoxia. See also anoxia, asphyxia.

hypoxemia

 [hi″pok-se´me-ah]
deficient oxygenation of the blood. The most reliable method for measuring the degree of hypoxemia is blood gas analysis to determine the partial pressure of oxygen in the arterial blood. Insufficient oxygenation of the blood may lead to hypoxia.

hypoxemia (hī·pk·sēˈ·mē·),

n condition in which oxygen levels in arterial blood are low. Typical symptoms are apnea, increased blood pressure, tachycardia, restlessness, stupor, coma, Cheyne-Stokes respiration, hypotension due to increased initial cardiac output that has rapidly fallen, ventricular fibrillation, and other conditions.

hypoxemia (hī´poksē´mēə),

n a deficient oxygenation of the blood.

hypoxemia

deficient oxygenation of the blood. The most reliable method for measuring the degree of hypoxemia is blood gas analysis to determine the partial pressure of oxygen in the arterial blood. Decreased oxygenation of the blood eventually leads to hypoxia.

Patients with more severe COPD frequently have hypoxemia and are treated with long-term oxygen therapy.
The purposes of this position statement are to: (1) provide an overview of the impact of hypoxemia and the impact of appropriate supplemental oxygen delivery on function, (2) to discuss the benefits of supplemental oxygen use in a variety of patient/client groups, and (3) to present the role of physical therapy in the use of assessment and titration of supplemental oxygen in patients especially during activity, including legal implications of titration.
