Table 1 (abstract P195). Doctors’ preferences for adjusting an FiO2 of 0.50 in a patient with acute respiratory distress syndrome (n = 654 to 655)

From: 38th International Symposium on Intensive Care and Emergency Medicine

PaO2 Increase No change Decrease
8 kPa 53% (49%-56%) 47% (43%-51%) 0% (0%-1%)
10 kPa 2% (1%-3%) 73% (70%-76%)* 25% (22%-28%)
12 kPa 0% (0%-1%) 26% (23%-29%)* 74% (71%-77%)
14 kPa 0% (0%-0%) 3% (2%-4%)* 97% (96%-98%)
  1. The scenario involves a patient expected to receive mechanical ventilation for at least 24 hours in the ICU. All proportions are percentages of respondents with 95% confidence intervals. *p < 0.001 for comparisons of proportions of “No change” versus adjacent lower PaO2 level (McNemar’s test)
