Blood gas analysis

General In a blood gas analysis (short: BGA) the concentrations of certain gases in the blood are measured. These gases, which include oxygen (O2) and carbon dioxide (CO2), have a certain partial pressure (pO2 and pCO2) in the blood, which should normally be stable and thus maintain the vitality of the organism. In addition, other … Blood gas analysis
