[Blood gas analysis in the intensive cardiac care unit]. / La rapida lettura dell'emogasanalisi in unità di terapia intensiva cardiologica.

ABSTRACT

Arterial blood gas (ABG) analysis is a simple and quick test that can provide multiple respiratory and metabolic parameters. The interpretation of ABG analysis and acid-base disorders represents one of the most complex chapters of clinical medicine. In this brief review, the authors propose a rational approach that sequentially analyzes the information offered by the ABG to allow a rapid classification of the respiratory, metabolic or mixed disorder. The patient's history and clinical-instrumental assessment are the framework in which to insert the information derived from the ABG analysis in order to characterize the critical heart patient.
