Table 2.
Study end‐points for patients randomly allocated to either the high‐flow nasal oxygen group or standard oxygen group. Values are median (IQR [range]) or number (proportion)
| High‐flow nasal oxygen group | Standard oxygen group | p value | |
|---|---|---|---|
| n = 49 | n = 45 | ||
| Total length of stay; days | 7 (6–9 [4–30]) | 9 (7–16 [4–120]) | 0.012 |
| ICU length of stay; days | 1 (1–2 [1–15]) | 1 (1–2 [1–23]) | 0.949 |
| Re‐admission to ICU | 1 (2.0%) | 7 (15.6%) | 0.026 |
| Six‐minute walk test; m | 214 (116–280 [40–380]) | 165 (98–251 [60–510]) | 0.330 |
| Lung function | |||
| FVC; l | 1.9 (1.6–2.3 [0.8–3.8]) | 1.9 (1.5–2.3 [0.9–3.5]) | 0.480 |
| FVC; % of predicted value | 57 (45–66 [31–102]) | 57 (47–69 [34–123]) | 0.990 |
| FEV1; l | 1.5 (1.1–1.7 [0.7–2.5]) | 1.2 (1.1–1.5 [0.5–2.7]) | 0.180 |
| FEV1; % of predicted value | 54 (42–64 [29–81]) | 53 (39–65 [18–83]) | 0.690 |
ICU, intensive care unit; FEV1, forced expiratory volume in one second; FVC, forced vital capacity.
