Interpretation of Arterial Blood Gases in the Emergency Patient

  • Ann Medinger


Arterial blood gas (ABG) analysis is a critical element in the modern diagnosis and management of pulmonary emergencies. There are no clinical findings that correlate specifically and well with pH, PaCO2 and PaO2 measurements. Knowledge of the abnormalities in pH, PaO2 and PacO2 allows the physician to direct early therapeutic and diagnostic efforts with the greatest lifesaving efficiency. Normal values are given in Appendix B.
