  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. 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 .

  5. Oxygen saturation (medicine) - Wikipedia

    en.wikipedia.org/wiki/Oxygen_saturation_(medicine)

    An SaO 2 (arterial oxygen saturation, as determined by an arterial blood gas test [8]) value below 90% indicates hypoxemia (which can also be caused by anemia). Hypoxemia due to low SaO 2 is indicated by cyanosis. Oxygen saturation can be measured in different tissues: [8]

  6. Respiratory failure - Wikipedia

    en.wikipedia.org/wiki/Respiratory_failure

    Arterial blood gas (ABG) assessment is considered the gold standard diagnostic test for establishing a diagnosis of respiratory failure. [1] This is because ABG can be used to measure blood oxygen levels (PaO2), and respiratory failure (all types) is characterized by a low blood oxygen level. [1]

  7. Hyperoxia test - Wikipedia

    en.wikipedia.org/wiki/Hyperoxia_test

    A hyperoxia test is a test that is performed—usually on an infant—to determine whether the patient's cyanosis is due to lung disease or a problem with blood circulation. It is performed by measuring the arterial blood gases of the patient while they breathe room air, then re-measuring the blood gases after the patient has breathed 100% ...

  8. 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 ]

  9. Respiratory acidosis - Wikipedia

    en.wikipedia.org/wiki/Respiratory_acidosis

    Diagnoses can be done by doing an ABG (Arterial Blood Gas) laboratory study, with a pH <7.35 and a PaCO2 >45 mmHg in an acute setting. Patients with COPD and other Chronic respiratory diseases will sometimes display higher level of PaCO2 with HCO3- >30 and normal pH. [citation needed] [2]
