Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Wether nasal prongs are effective in maintaining oxygen saturation during periods of apnea in patients with simulated cervical spine immobilisationTimepoint: 6 minutes or untill the saturation falls till 95% | — |
Secondary
| Measure | Time frame |
|---|---|
| To compare the safe apnoea time in group which will be only preoxygenated as compared to group receiving oxygen insufflation through nasal prongs during apneoa in addition to preoxygenation.Timepoint: 6 minutes or until the saturation falls to 95% | — |
