ABSTRACT

The oxygenation indices are defined as the numerical expression of the relationship that exists between the gasometric values of the arterial oxygen pressure (PaO₂) and the arterial pressure of carbon dioxide (PaCO₂) at the level of the alveoli; they represent the function of the respiratory unit capillary alveolus membrane; at the pathophysiological level they represent hypoxemia. The utility of these numbers ranges from establishing a diagnostic impression of a lung disease to prognostic orientation thereof. It is an affordable and accessible tool to most medical units. The objective of this paper is to describe the usefulness of oxygenation indices in our daily medical practice.
