HYPEROXIA AND RESPIRATORY DYSFUNCTION AT ICU ADMISSION ARE ASSOCIATED WITH POOR OUTCOMES IN MECHANICALLY VENTILATED PATIENTS

Objective: to identify the association of hyperoxia at time Intensive Care Unit (ICU) admission with clinical outcomes in adult patients on invasive mechanical ventilation and respiratory dysfunction defined by a PaO2/FIO2 ratio (P/F) below 300. Methods: retrospective cohort observational study data from admitted general ICU, 8 beds university hospital. Hyperoxia was as PaO2 > 120mmHg were classified 4 subgroups: 1.hyperoxia P/F 300, 2. ? 3.no 4. no Results: total 129 included. present one third (43, 33.3%) all patients. It more frequent without (P/F 30 54 individuals 55.6%) comparison those 13 88, 14.7%), p=0,044. The ICU mortality not different among subgroups; however, length stay greater subgroup < Conclusion: admission, mechanically ventilated associated worse ratio.
