Blood gas is a laboratory test of blood where the purpose is primarily to measure ventilation and oxygenation. The source is generally noted by an added word to the beginning; arterial blood gases come from arteries, venous blood gases come from veins and capillary blood gases come from capillaries.

Famous quotes containing the words blood and/or gas:

    Later,
    when blood and eggs and breasts
    dropped onto me,
    Daddy and his whiskey breath
    made a long midnight visit
    in a dream that is not a dream....
    Anne Sexton (1928–1974)

    Droning a drowsy syncopated tune,
    Rocking back and forth to a mellow croon,
    I heard a Negro play.

    Down on Lenox Avenue the other night
    By the pale dull pallor of an old gas light
    Langston Hughes (1902–1967)
