Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Incidence of oxygen desaturation Absolute incidence of oxygen desaturation less than 90% as measured by pulse oximetry,Onygen reserve index(ORI), And arterial oxygen saturation, via ABG 2. Group differences between oxygenation indices Measured via pulse oximetry, ORI and Pao2 Timepoint: 1.Baseline- Before preoxygenation. 2.At the end of adequate/most optimal preoxygenation 3.At the end of successful endotracheal intubation confirmed by serial capnography. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1.Group differences in time of desaturation, 2.Group differences in incidence of Nadir of oxygenation indices. 3.Relative incidence of arterial desaturation with respect to a.Duration of intubation b.Number of attempts. c.Intubating conditions. d.Patient factors-BMI, baseline Pao2, baseline p/f ratio, sepsis score. 4. Correlation between measured Pa02 and ORI Timepoint: 12 months | — |
