- *Data were presented as mean ± standard deviation (median, range). a was statistically significant compared with COT group, b was statistically significant compared with HFJV group, c was statistically significant compared with NFJV group
- There were significant differences among the three groups in PaO2, lactic acid and procedure duration (P < 0.001, P = 0.005, P = 0.038). Moreover, PaO2 of HFJV group was significantly higher than that of COT and NFJV group. Lactic acid and procedure duration of HFJV group was significantly higher than that of COT group
- COT conventional oxygen therapy; NFJV normal frequency jet ventilation; HFJV high frequency jet ventilation
