Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Evaluate the value of the rapid and shallow breathing index collected by means of a ventilometer and obtained by means of mechanical ventilation parameters (in support pressure and continuous positive pressure in the airways with pressure and flow triggering). Data collected during the spontaneous breathing test. It is expected to find a significantly lower IRRS value in the support pressure than in the ventilometer, with no difference between this and that obtained in CPAP mode. For such comparisons, a p value of 0.05 will be used. | — |
Secondary
| Measure | Time frame |
|---|---|
| Evaluate the value of tidal volume and respiratory frequency collected by means of a ventilometer and that obtained by means of mechanical ventilation parameters (in support pressure and continuous positive pressure in the airways with pressure and flow triggering). It is expected to find significantly higher tidal volume and significantly lower respiratory rate values ??in support pressure than in the ventilometer, with no difference between these and that obtained in CPAP mode. Data collected during the spontaneous breathing test. For such comparisons, a p value of 0.05 will be used. | — |
