ABSTRACT

Introduction: The oxygenation index (OI) is a new indicator whose predictive value has not been studied in adults.
Objectives: To determine the usefulness of the oxygenation index as a marker of mortality in adult patients with acute respiratory distress syndrome (ARDS).
Methods: An analytical and longitudinal study in patients who met the diagnostic criteria for ARDS with settling time less than 36 hours is presented. Oxygenation calculations were performed within 24 hours, with consecutive samples at 48 and 72 hours.
Results: The average age in the group of survivors was 35,6 years old vs. 53,5 years in non-survivors. The average rate of oxygenation in the first 24 hours in the group of survivors was 11, whereas in non-survivors of 23,7. 48 hours measure had an average of 7,4 in survivors and 17,1 in non-survivors; also, in 72 hours measure an average of 9.5 in the group of survivors was obtained vs. 18,8 in non-survivors.
Conclusions: The oxygenation index is useful as a marker of mortality in adults in the early acute phase of ARDS when compared with other parameters of oxygenation.
