Table 2 (abstract P195). Doctors’ preferences for adjusting an FiO2 of 0.50 in a patient with chronic obstructive pulmonary disease with known habitual hypercapnia (n = 649)

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

PaO2 Increase No change Decrease
8 kPa 11% (9%-14%) 85% (82%-87%) 4% (3%-6%)
10 kPa 1% (0%-2%) 38% (34%-42%)* 61% (58%-65%)
12 kPa 0% (0%-1%) 4% (3%-6%)* 95%(93%-96%)
14 kPa 0% (0%-1%) 1% (0%-2%)* 99% (97%-99%)
  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)
