  2. Arterial blood gas test - Wikipedia

    en.wikipedia.org/wiki/Arterial_blood_gas_test

    An arterial blood gas (ABG) test, or arterial blood gas analysis (ABGA) measures the amounts of arterial gases, such as oxygen and carbon dioxide. An ABG test requires that a small volume of blood be drawn from the radial artery with a syringe and a thin needle , [ 1 ] but sometimes the femoral artery in the groin or another site is used.

  3. Blood gas test - Wikipedia

    en.wikipedia.org/wiki/Blood_gas_test

    A blood gas test or blood gas analysis tests blood to measure blood gas tension values, it also measures blood pH, and the level and base excess of bicarbonate.The source of the blood is reflected in the name of each test; arterial blood gases come from arteries, venous blood gases come from veins and capillary blood gases come from capillaries. [1]

  4. Arterial line - Wikipedia

    en.wikipedia.org/wiki/Arterial_line

    Arterial lines are most commonly used in intensive care medicine and anesthesia to monitor blood pressure directly and in real-time (rather than by intermittent and indirect measurement) and to obtain samples for arterial blood gas analysis.

  5. Pulmonary function testing - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_function_testing

    Arterial blood gases (ABGs) are a helpful measurement in pulmonary function testing in selected patients. The primary role of measuring ABGs in individuals that are healthy and stable is to confirm hypoventilation when it is suspected on the basis of medical history, such as respiratory muscle weakness or advanced COPD. [citation needed]

  6. Blood gas tension - Wikipedia

    en.wikipedia.org/wiki/Blood_gas_tension

    Blood gas tension refers to the partial pressure of gases in blood. [1] There are several significant purposes for measuring gas tension. [2] The most common gas tensions measured are oxygen tension (P x O 2), carbon dioxide tension (P x CO 2) and carbon monoxide tension (P x CO). [3]

  7. Methemoglobinemia - Wikipedia

    en.wikipedia.org/wiki/Methemoglobinemia

    The congenital form of methemoglobinemia has an autosomal recessive pattern of inheritance. Due to a deficiency of the enzyme diaphorase I (cytochrome b5 reductase), methemoglobin levels rise and the blood of met-Hb patients has reduced oxygen-carrying capacity. Instead of being red in color, the arterial blood of met-Hb patients is brown.

  8. Acidosis - Wikipedia

    en.wikipedia.org/wiki/Acidosis

    Arterial blood gas analysis and other tests are required to separate the main causes. In certain situations the main cause is clear. In certain situations the main cause is clear. For instance, a diabetic with ketoacidosis is a recognizable case where the main cause of acidemia is essentially obvious.

  9. Alveolar–arterial gradient - Wikipedia

    en.wikipedia.org/wiki/Alveolar–arterial_gradient

    The Alveolar–arterial gradient (A-aO 2, [1] or A–a gradient), is a measure of the difference between the alveolar concentration (A) of oxygen and the arterial (a) concentration of oxygen.
