This table shows the indication to start high-flow nasal cannula oxygen therapy, underlying diagnoses, vital parameters and arterial blood gas measures for both patients for whom high-flow nasal cannula oxygen therapy was successfully and unsuccessfully administered.
Percentages are shown per column and CIs are 95% bias-corrected and accelerated CIs.
*The total does not add up to 100%, since there were two deaths at the IMCU, which were excluded from these analyses.
CRP, C reactive protein; IMCU, intermediate care unit; OR, operating room.
