hypoxemia

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.

hy·pox·e·mi·a

(hī'pok-sē'mē-ă),
Subnormal oxygenation of arterial blood, short of anoxia.
[hypo- + oxygen, + G. haima, blood]

hypoxemia

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

hypoxemia

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

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

Hypoxia ↓ O2 in the blood

hy·pox·e·mi·a

(hī'pok-sē'mē-ă)
Subnormal oxygenation of arterial blood, short of anoxia.
Synonym(s): hypoxaemia.
[hypo- + oxygen, + G. haima, blood]

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·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.

hy·pox·e·mi·a

(hī'pok-sē'mē-ă)
Subnormal oxygenation of arterial blood, short of anoxia.
Synonym(s): hypoxaemia.
[hypo- + oxygen, + G. haima, blood]

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.
