Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Prolongation of time for saturation to come from 100% to 92% during laryngoscopy 2. Increase in arterial oxygen due to supplemental oxygen insufflationTimepoint: 1. Arterial oxygen samples shall be taken thrice. Once before oxygenation is initiated ie time 0, then at 3 minutes of start of study and also after intubation has been confirmed. 2. After giving muscle relaxant ie. roughly 4 minutes after start of study, time taken for hemoglobin oxygen saturation to fall to 92% shall be noted. 3. Time required for saturation to recover to 100% once it has fallen to below 92% shall also be noted. | — |
