These tests help determine whether it is primarily respiratory (due to an imbalance between the amount of oxygen coming in and CO2 being released) or metabolic (due to increased or decreased amounts of bicarbonate in the blood). They also help monitor treatment until acid-base balance is restored.
Jazz is a music genre that originated from African American communities of New Orleans in the United States during the late 19th and early 20th centuries.
As discussed in more detail below, jazz began as a West Coast slang term around 1912, the meaning of which varied but it did not initially refer to music. Jazz came to mean jazz music in Chicago around 1915.
