Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Success of NIPPV | through intervention completion, with an average of 10 days | The success of NIPPV application was defined empirically as use of ≥ 2 hours per day and the failure as use of \< 2 hours for a day or conversion to invasive positive pressure ventilation via tracheostomy or refuse to apply NIPPV during hospitalization. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Lenght of stay | through intervention completion, with an average of 10 days | The length of stay (LOS) was defined as the interval between admission and hospital discharge, and calculated as the number of midnights between admission and discharge from the hospital. |
