ICU - intensive care unit; PEEP - positive-end expiratory pressure; PaCO2 - arterial carbon dioxide tension; PaO2 - arterial oxygen tension; FiO2 - fractional inspired oxygen ratio; Hb - hemoglobin; Ur - urea; Cr - creatinine; GFR - glomerular filtration rate (MDRD); APACHE II - Acute Physiology and Chronic Health Evaluation II. The Student t test and Fisher’s exact test were used for analysis and significance was set at p<0.05. The results are expressed as numbers (%) and median±SD.
