blood-gas analysis

blood-gas analysis

The evaluation of arterial blood for O2, CO2 and bicarbonate content, as well as blood pH, to determine oxygenation and acid base status. Specimens for BGA must be obtained from the arteries—radial, brachial, femoral—to avoid misinterpretation of the results, drawn in a vacuum tube, and transported immediately to the lab on ice.
